Otters and the use of electrical fencing/traps

 In 2022 I learnt quite by accident that some tenants in the Staple Hill area of Bristol were using equipment purchased from Ebay and Amazon to create electrical fencing to deter otters from koi carp ponds. This is also going on in other areas with carp ponds.

I went through DEFRA who were utterly useless and did not seem to give a damn about the matter despite, and I quote:

"Otters are designated and protected as European protected species ( EPS ). EPS are protected under the Conservation of Habitats and Species Regulations 2017. It is an offence to: deliberately kill, injure, disturb or capture them."

So after the usual run around I contacted Bristol City Council Animal Welfare 🙄 Department and I was given the shrug and "nothing to do with us" (BCC just keeps on 'giving'). Despite otter deaths on one particular road the idea of fencing and an animal road underpass was "beyond council local policy" whatever that means.

My next port of call was the supposed be all and end all on these things -Natural England. I emailed, got passed along, ignored and then after further efforts to be a pest got this response in January but Natural England does not seem to give a ****.

"Hello Terry

"I have had an email from another colleague about your query which I thought might be useful for you. He has read the Natural England guidance that was on the facebook thread and had the following comment:

"Although this refers to development and habitat loss I think the people with the pond need to be careful how they mitigate against the otters to protect the pond. The extract includes ‘uses otter-proof fences to stop otters getting on to development sites’.

"He suggests contacting Natural England for a clear answer on what people are allowed to do to protect an established pond.

"I believe this is the quote in question.

"Avoidance, mitigation and compensation measures

Look for examples of avoidance, mitigation or compensation plans in the development proposal. The proposal could avoid:

· work on or near the water body and known otter habitat, including work to road crossings and culverts

· disturbance effects, for example, by leaving a buffer zone along a river

· night works

The size of the buffer zone along the stretch of water will vary depending on:

· how otters use the area

· the type of vegetation at the site

· the level of existing background disturbance

· the level of proposed disturbance

Where avoidance measures are not possible, mitigation measures could include designing the development so that it:

· retains otter habitats in the water body and bank

· uses otter-proof fences to stop otters getting into development sites

"Otters are highly territorial animals with large home ranges. Depending on the quality of the habitat and availability of food, males can range along rivers for 35km. Otters will continue to try and use routes if alternatives are not included in a mitigation strategy.

So I am now chasing NE up again. It is about time people began to learn to live with wildlife and find ways around problems without the use of devices that might harm wildlife.

Environmental Destroyers Win Again. Will A Prosecution Worry Them?

 Simple answer is "no" and the excuse of "we had no idea" will be the defence. Three times I have been called in when developers "Had no idea" that they were destroying an area with badger setts in and in one case they replaced vegetation and signs for workers to not enter area.  As I pointed out to them it was that or reporting and prosecution (and very bad press)

Developer fells mature woodland that had bats and owls in area

How the plot used to look. The trees formed part of the large wooded garden of a property in Corfe Mullen, Dorset owned by an elderly man until he died last year - MAX WILLCOCK/BNPS

Villagers in Dorset have condemned the felling of 20 trees thought to have been the home of bats and owls as an act of “environmental vandalism”.

More than 20 mature trees were cut down in a single day in the garden of a house in Corfe Mullen in September, previously owned by an elderly man who died last year.

The plot had tall conifers, ash and oak, thought to have been over 100 years old. Residents have reported it to the police.

A survey of a nearby property had found three bat roosts, recorded after 2010, including evidence of Greater Horseshoe bats.

It is not yet known if a wildlife survey was carried out before the trees were cut down but it believed they were home to bats, owls and woodpeckers

The house, with its acre of land, had recently been bought by a developer when residents were woken at 7am to the sound of three excavators and tree surgeons starting work, bringing in lights as night fell and working until 9pm to clear the site.

Jackie Bonham, 55, has lived next to the property for 17 years and has described the shock of seeing the greenery destroyed.

She said: “Everyone is distressed and disturbed by this sudden and shocking development.

“I first knew about the work when my kitchen started shaking and all I could hear was chainsaws and machinery.

“As neighbours we expected some work to be done on the property but there was no planning application, so it came as a surprise to us all when we realised what was happening.

“We are all really upset, mainly for the wildlife who have lost their home and were not given a moment’s thought throughout the work.

“They completely destroyed an eco-system in one day and all the wildlife in it. It’s devastating.

“The previous owner, James White, loved his garden and it gave him life after his wife passed away. He would be devastated if he saw what it has become.

“On the day this policewoman came out and tried to ask them for any survey [of wildlife] and they said they’d email it through, a bat survey. They sent it the next day and it looked like a bit of paper they’d signed themselves.

“There’s bats in the area, so with historical evidence of bat activity it’s likely there are roosts nearby. When next door neighbours applied for planning permission on their garage they had to have a survey. Ten feet away they could take the huge conifer trees down with nothing.”

Local residents have been left devastated after developers turned a wooded wildlife haven into a barren landscape without warning - MAX WILLCOCK/BNPS

Neighbour and former soldier Gerrard Hayes, 83, said he went out to find one of his trees being hacked down before he put a stop to it.

He claims the work left the tree unsafe and alleges the tree surgeons tried to charge him £800 to fell it, even though they had caused the damage.

He said: “All I saw was a couple of workers starting to cut down my tree at the bottom of my garden that backs on to the site, I couldn’t believe it.

“They started cutting one side of the tree in my back garden before realising it was on my property and stopped.

‘Environmental vandalism’

“I told them they had left the tree unsafe and it could fall at any moment given a good gust of wind.

“They said I was liable if the tree killed someone and told me I’d have to pay £800 in cash in order for them to remove it, which I refused.

“My neighbour has told his children not to go near their shed in fear that the tree could fall on them at any time and severely injure them or worse.

“The woodland was all so beautiful before all this work and what has happened is pure environmental vandalism.”

Dorset Council said: “We haven’t received a planning application for the site. Land clearance would not be development within Dorset Council’s control and the trees were not subject to a tree preservation order.

“Damage to a protected habitat is a criminal offence and a police matter.” Dorset Police have been approached for comment.

A ‘very rare’ predator lurking in their garden -Some Notes and Pine Marten Releases in the 1990s

 This item is interesting as really the Pine marten should not have been where it was. We do know that there have been successful releases and litters around the UK of a mammal humans slaughtered on sight. But I have in my EAR files reports of pine martens in the 1990s and in the Somerset area where official groups told me (as if I was stupid so why report the matter) they were not. 

My sources were credible and experience persons -one a naturalist. Where exactly were these sightings in Somerset? Not telling because back then, as now, we know that there are plenty of people wanting to get rid of them illegally and, of course, the 'sportsmen' who want a rarity.

But how did the Somerset pine martens escape the attention of the people who should know they were there?  Simple; the "people who should know" were never told so could not take credit for the discovery and definitely could not, as they would have, given out a location. The other question is how long had the martens been at the locations?  We had no idea because anyone who sighted them kept quiet and myself and the naturalist involved decided to not even snoop around the areas in case we were seen.

In the 1990s I discovered the open secret that a group had been breeding and releasing pairs of European wildcats around the country to fill in the niche left by the actual extinct wild cats (including on the Scottish borders). Who were these people? Where did they get these cats? Organisations in the "know" did know but claimed that they did not but were aware of these cats in the areas reported.  It is also probable that this group released pine martens before the official release project. 

Today I have heard of pine marten being bred for the "exotic animal" trade rather as porcupines, meerkats, raccoon dogs and others are.  These animals do escape and I have reported on them in the past on the Exotic Animals Register blog as well as Face Book page.

Was this Scottish marten just lost or an escapee pet? It is highly probable that we will never know but I hope it finds suitable habitat soon.

Homeowner discovers ‘very rare’ predator lurking in their garden: ‘This may be a newsworthy sighting’

A Reddit user from Scotland recently spied a rare predator in their backyard.

They took to r/AnimalID to put a finger on the wily mammal, as it was threatening birds perched in the low limb of a tree.

In the 15-second video, the animal climbed atop a fence and looked around before scurrying away.

Users formed a consensus that the animal is a pine marten.

“It’s my understanding that those guys are currently very rare in Scotland,” one commenter wrote. “This may be a newsworthy sighting. I would strongly suggest you contact a local conservation agency and send them this footage. If he’s killing your birds they’ll likely relocate him for you.”

Another said: “Pretty cool to see them, they’re pretty shy most of the time. And rare these days.”

The creature was once found all over Britain, but it was hunted mercilessly until it was given legal protection in 1988, according to NatureScot. Scotland is now home to about 3,700 adult pine martens.

Pine martens prefer to live in woodlands, often in hollow trees, old squirrel, or old bird nests, and require 86 to 166 hectares (213 to 410 acres) of territory. They survive on rodents, birds, eggs, insects, and fruit.

“The Scottish Wildlife Trust has been running a successful pine marten recovery programme, and sightings of these elusive creatures are becoming more common,” according to Experience Scotland’s Wild.

The pine marten population in Northern Ireland is bouncing back as well, nearly doubling in five years, the BBC reported in May.

The species could also help the red squirrel population, as those native rodents have adapted to live among pine martens, while the invasive gray squirrel has not.

“They say that once a squirrel could run from one side of Europe to the other without touching the ground, leaping from tree to tree,” one user wrote. “And that he’d be followed the whole way by a hungry pine marten.”

Another said: “They are amazing creatures. Definitely bring any cats and small livestock indoors. Do not approach because they are sometimes cranky. Call a wildlife management official if you don’t want it around.”

Always The Negative News On Wildlife Rescues -some personal comments

 The fact that wildlife rescues of varying sizes are closing down around the UK and that thousands of animals may suffer or simply face being put down for minor injuries does not interest the press and media. It just is not a "sexy" enough news story.

Now, someone running a wildlife rescue who has embezzled £190, 000 is a "very sexy" story worth posting everywhere.

With £190,000 Bristol could get the wildlife rescue it desperately needs. Any town or city could get a much needed sanctuary-cum-wildlife rescue. But yet another rescue is in the news and we know what stories like this do: it makes possible donators think that their money is going to be used for someone's personal gain and not in treating wildlife. Rather than give an over view of wildlife rescues to balance things out all they do is report on "the crook".

And what the **** was he thinking he was doing?  He has now blighted any and every rescue going as people are not going to "throw money away" to embezzlers. And at a time when the fight for wildlife rescue and treatment is critical and people are already few and far between in helping rescues.

This is something we just do not need. 

Wildlife sanctuary owner used £190,000 of donations to buy himself a house

The Telegraph https://uk.yahoo.com/style/wildlife-sanctuary-owner-used-190-130743229.html

Chris Tucker is a former animal rights activist who was jailed in 1992 for an attack on a McDonald’s restaurant - Simon Jones/News Group Newspapers Ltd

The owner of a wildlife sanctuary has been convicted of fraud after using tens of thousands of pounds of public donations to buy a house.

Chris Tucker, 59, a former animal rights activist who was jailed in 1992 for an attack on a McDonald’s restaurant, was convicted on Friday at Lewes Crown Court of fraudulently using £190,000 of public donations to pay for his own property. He is due to be sentenced next month.

The money was raised for Bexhill and Hastings Wildlife Rescue and Sanctuary between 2017 and January 2019, which Tucker claimed would help to secure his semi-detached house – where it is based – in a trust or community interest company.

He added that the money would be safeguarded officially for good causes and not benefit him or anyone else personally.

However, in November 2019, police received an allegation that Tucker had used the public-generated funds to buy out his ex-partner and take sole ownership of the property.

Tucker, of Chantry Avenue, Bexhill, was arrested and subsequently charged with fraud by false representation.

He denied the offence, but it was proven that he acted dishonestly in order to acquire a valuable property in his sole name.

After the verdict, Detective Constable Jake O’Reilly said: “In November 2019, Sussex Police were contacted following an allegation that Tucker had made promises to sign over his property to a trust which would oversee the future running of Bexhill and Hastings Wildlife Sanctuary and Rescue if enough money could be raised by supporters.

“When this amount was achieved, it was alleged that Tucker had then acted dishonestly and taken sole control of a large property where the rescue is based.

“The result of this fraud was that Tucker had acquired a large mortgage-free house and the rescue – which is not a registered charity – was not safeguarded by an independent trust which would make collective decisions on its future.”

‘Long and complex fraud enquiry’

Police Investigator Peters, who pieced together the investigation between 2019 and 2023, added: “This was a long and complex fraud enquiry involving a vast amount of donations and donors who were not given a true account of what would happen to their money. I am pleased justice has been served.”

On Monday 9 October, at Hove Crown Court, Tucker was further convicted of one count of contempt of court in relation to messages posted on social media, which he pleaded guilty to, and his sentencing was adjourned to Friday 10 November 2023.

In 1992, Tucker was jailed for 15 months after he terrorised staff and customers by throwing what appeared to be a bomb across the counter of a crowded McDonald’s restaurant in Kensington, west London.

The court heard that Tucker, who had several previous convictions involving animal rights activities, threw the canister after asking a staff member whether they killed animals in the restaurants.

After he was convicted, Tucker was banned from entering all McDonald’s restaurants in Britain.

Last night, Tucker told the Telegraph that he was ashamed of his past, adding: “I admit what I did at McDonald’s was disgusting and inexcusable. I should never have done it.”

He said he was now making arrangements to sign over half of his house to the wildlife charity.

Rats -A Solution Without Cruelty and Its Safe For Predators

People ask whether rats are a problem in the UK? The simple answer is yes. The brown (Rattus norvegicus) and black (Rattus rattus ) rats are the only two species in the UK if we ignore the number of exotic rodents being bred here and just concentrate on the wild ones. We can only estimate so a figure may be exaggerated but the one seemingly accepted is a population of 250 million. 

Even with a suggested lifespan of only 2-3 years a female rat typically births six litters a year consisting of up to 12 rat pups, although 5-10 pups are more common. Rats reach sexual maturity after nine weeks, meaning that a population can swell from two rats to around 1,250 in one year, with the potential to grow exponentially.

The natural predator of the rat in the countryside, villages, towns and cities are the cat (these days feral cats probably take more rats than pet cats) and the fox. Owls and hawks will also take rats and this is where the problems begin for wildlife because the solution of most local authorities is to use rodenticides and secondary poisoning of predators is a major problem.

If you listen to pest control companies, who have a large financial interest in the matter, rodenticides are the best solution. I have had three pest control officers from Bristol tell me to my face that the poison they use does not affect wildlife and no other animal can be affected by ingesting poisoned rats. An outright lie. By supermarkets and shops you tend to see metal boxes attached to lamp posts and these are designed so that if the rat enters it is "zapped" and killed. 

There is one shopping area near me where these traps are always smashed. I found out that locals were doing this as curious small birds were entering the traps and being killed and the final straw was an electrocuted hedgehog. Figures on small wildlife killed by these traps is not available and if you try to search for that information all you will get is page after page of pest control adverts, recommendations.  People on The Red Island tend not to care because "out of sight out of mind".

There are various mouse and rat traps that can maim and leave a rodents to die slowly and the larger traps, as with the "zappers" and these are again deadly to small mammals.

Back in the 1970s I was reading in a German magazine how a small town had cut its rat population right down and I guessed more poisoning and trapping but I was wrong. Someone had suggested, and the local authority approved the idea, that bait with some chemical in it be placed out for rats and the chemical was a contraceptive one. I have tried over the years to find the article or the town and failed -even with the internet.  The question is whether it is better to sell off the shelf rodenticides to the public who have no idea how to use it or for local authorities to employ pest control people who then use rodenticide or use something that will affect the rats and no other wildlife?

Yes, pest controllers are heavily invested in the use of poisons so that would affect their livelihood but at this point in time we have to start thinking about wildlife which is being killed in droves as well as the effect on the environment.  I have already discussed elsewhere how you can get rats out of your home without poison here

And research work has been carried out of how to use a contraceptive in bait to deal with rodents and there is a paper on the matter -Fertility Control for Wildlife: A European Perspective by Giovanna Massei https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9913817/

Quote:

"ContraPest® is a liquid contraceptive designed to reduce fertility in rats and delivered in a tray, placed inside a box, to minimise use by non-target species [78]. ContraPest suppresses fertility in males, by preventing sperm maturation and motility, and in females, by decreasing the number of eggs that are ovulated [79,80]. This contraceptive must be delivered daily for at least 50 days in order to inhibit production of litters for around three successive breeding rounds, as shown in captive studies with Norway rats [81,82]. In this species ContraPest decreased the weight of reproductive organs but had no effect on adrenal, kidney, spleen and liver weights compared to control animals [82]. The efficacy and potential side effects of ContraPest on free-living rats has not been reported, as only information on the efficacy of ContraPest combined with a rodenticide is available [78].

"EP-1, based on synthetic steroids, has been proved to inhibit the fertility of males and females of many rodent species in China, Tanzania, Zambia, and Indonesia [83,84,85,86,87] in captivity and field trials. In several species, a treatment period of about 7 days in laboratory studies or a single baiting with EP-1 in field conditions, are sufficient to induce infertility [87]. In females the most common response to EP-1 is an enlargement of the uterus which result in reduced conceptions and/or litter sizes. In males EP-1 inhibits the function of the testis, epididymis and seminal vesicles for different periods of time depending on the dose [75,87] and in both sexes the effects are temporary and fully reversible. Side effects of these synthetic hormones in rodents include production of smaller pups in striped field mice (Apodemus agrarius) dosed with EP-1 [88] and in Brandt’s vole (Lasiopodomys brandtii) treated with quinestrol [74]. EP-1, widely tested on many rodent species, has not been used in field trials in Europe and its use might not be acceptable until the potential effects of the hormones on the food chain and on the environment have been assessed."

Local authorities claiming to have a credible environmental stance need to step up and this is probably one of the easiest solutions to preventing wildlife deaths and damage to the environment while taking care of rats.

It is a win-win solution unless there is heavy investing in pest control for financial gain.

Ashton Vale Wildlife Survey 2024 -You Can Survey Your Own Area, Too

 Originally from an American site but is worth posting here. Since 1995 I have made sure that there are berries, leaves are left on the ground (for mulch) and I never cut back seed heads since birds help spread the seeds.

In fact the robin and other visitors are enjoying the insects to be found on the bushes and trees. The wood pigeons had the summer and autumn berries but still grab what they can.

It is interesting that Avon Wildlife Trust, when you enter Ashton Vale into its search engine produces the following message:

"Sorry! We can’t find any events or nature reserves that match your search. Please try again with a different search."

Common adder (c)2023 Benny Trapp

Now I have been keeping records since I moved to Ashton Vale in 1994 and first day I read and saw what AWT had to say about the area: "Wildlife deprivation zone" yet that first night I had two barn owls swoop low overhead, heard tawny owls and there were LOTS of beetles and insects and two of the largest hedgehogs I had ever seen. And looking out of my kitchen window that same night I saw a pair of foxes trotting up the road.

I found shrews, frogs and much more and so I contacted the Trust but was told quite clearly that I needed to be a member to submit information. Their loss not mine.

It takes very little to encourage wildlife into your garden and even a water source attracts (make sure there are stones so that any hedgehog falling in can get out!).

In 2024 I would like to put together a basic survey but the question is whether anyone will bother sending in information and photos
