Having started a large mammal survey in Bristol during 2022 (it failed as the feedback from wildlife groups was...minimal by which I mean one person). I knew there were otters within my area so I contacted the Greater Bristol Otter Group. I even posted messages on the Bristol Naturalist Society and Bristol Nature Network Face Book pages. Nothing.
I was somewhat concerned about the number of otters I had heard were dying on roads in the City and County. By mid-January, 2023 I gave up and posted out the following:
"What is going on??
"Our aim is to record otter presence in the Bristol area in order to gain a greater understanding of Bristol’s otter population while working alongside similar interest groups to exchange knowledge and ideas. Findings are reported to the Bristol Regional Environmental Records Centre (BRERC) which helps with research and reporting on otter presence in order to identify patterns of behaviour and also the impact of human interaction."
"Hi Terry,
"I have just looked through our database and mapped all our otter locations and unfortunately it appears we have only ever received one otter from Bristol in 2014. I have attached the PM form for this otter as well as its location on the map.
"We were surprised to discover that we have only had one otter from Bristol and upon further digging I found that we do still have a contact from the Environment Agency that covers all of North Wessex. It seems from previous emails that we have been cc'ed in that there may be a freezer full of otters in Bristol that we were unaware of, but we are yet to receive them.
"At the moment, we are at full capacity with our freezer space and have had to put a temporary halt on post-mortems, so we can't receive anymore. However, once we get going again, I will try to get in contact with someone down in Bristol and see if we can arrange to deliver the otters to Cardiff. Once we do, I will be sure that we send you the location and post-mortem results, but this may take several months.
"We would love to help you with your work in preventing more otter deaths, so sorry we couldn't be of more help.
Many thanks,
signed
I thanked the team and asked to be kept in touch with any results from otters in my area and eventually got another response:
"Hi Terry,
"Just to update you, we had a delivery from the Greater Bristol Otter Group on Friday 20th. I've updated the map so there is now three otters that have been delivered to us from the county of Bristol. I have attached the closeup of the location of these otters as it appears two of them were located very close from each other on the A4174. We don't have the PM report for these yet as that will take several months, however please let me know if you would like them.
"After talking with GBOG and looking into our records, I would like to confirm that the group has been sending us otters over the past several years. However, as they cover the Greater Bristol area, it means that they also include the surrounding counties, such as Somerset and Gloucestershire. In the attachments, I have shared with you the location of the otters that were delivered to us by GBOG on Friday. As you can see, most of them were located in Somerset. I have also included a wider view map, showing that dead otters are being widely reported across Wessex, however as Bristol is a more urban area they are perhaps less likely to be found there.
"I hope this helps clear up any confusion that may have arisen and please let me know if we can do anything else to help.
"Many thanks,
signed"

Closeup of Bristol otter deaths
Well, I joined the Greater Bristol Otter Group but it wasn't getting me anywhere and their last website post appears to have been from 2014. So, to help move things along I posted some otter news and even raised the subject of koi carp owners using "electrical devices" to deter otters.
The following item I posted on 4th July, 2023 and asked whether that came within the GBOG area?
rescue "At
7am we were called about a small otter pup lying on the path by Tems Beck in
Giggleswick. It had been seen the previous night with an adult, and then again,
but alone this morning. The finder Tim, checked on him an hour after first
spotting him, and he was still there, and he had been seen earlier by someone
else. Tim called the police and RSPCA, but had no joy and fortunately got our
number. Jane
Carpenter was there within about 10 minutes, and
Tim had waited with the otter. This little man was not trying to get away, but
he was trying to give a good bite.
"We followed the otter protocol from the last time
we rescued a pup, warmed him up and got straight onto our friend Dave Webb from
the UK Wild Otter Trust so that we could arrange a specialist rescue place and
transport for 'Chewbacca'. After 'Chewy' enjoyed a little salmon, he became
very weak and his little body started to shut down, and he gave just up. There
was obviously something very wrong for him to have been abandoned and then for
him to not try to escape, and then pass so quickly. "
The rescue attached some microscopy slides/clips that
they took and I will attach those here so that you can see.
"The pathologist carries
out, via Bristol Uni Post Mortem Services, all of the PMs on foxes submitted as
part of the Fox Deaths Project -I am sure you know of his work? I
contacted Mr. ****** and sent him the above and attachments and he responded:
"I’m not sure of the
magnification but the still images be of a fluke. There has been very little
work on endoparasites in otters and I would be very keen to do a diagnostic PM
on this cub. A nematode Pseudoterranova spp. and an acantocephalan have been
identified in gut contents. It should be noted that some parasites found in the
gut may be parasites of fish prey rather than of the otter."
The rescue explained that the Environment Agency had the otter and it was hoped the pup could be diverted to Bristol so I sent the pathologist's response to Cardiff:
"Unfortunately I received that reply after I was told that the otter was heading your way. I wondered whether there would be any way of having Mr. ***** carry out a diagnostic PM on the cub? My apologies if that is trampling over any protocols I am not aware of but I am trying to fix a miscommunication and as the rescue were concerned about any health issues in the local otters that might need dealing with I thought I would ask.
Again, apologies for any trampling on protocols.
Warm regards"
The pathologist was concerned that the amount of transport time and back and forth might mean autolysis was setting in (In biology, autolysis, more commonly known as self-digestion, refers to the destruction of a cell through the action of its own enzymes. It may also refer to the digestion of an enzyme by another molecule of the same enzyme.) I assumed that the pup had not been diverted to Bristol which was a pity but...
HOW OTTERS ARE PROTECTED
- deliberately kill, injure, disturb or capture them
- possess, control or transport them (alive or dead)
- disturb otters while they occupy a structure or place used for shelter or protection
- obstruct access to a place of shelter or protection
"“I have (since) found an example of an Environment Agency grill in Mousehole with a much greater width between the bars which would allow otters to pass. It is unlikely that Pigeon House stream grill is owned or installed by the Environment Agency as there is no sign stating this so it is likely to be owned by BCC.
“Despite the disturbing deaths of these two otters, and several requests by a number of people including me, nothing has been done in the last six months to address the problem. The current harbourside litter bin campaign states that BCC likes otters but clearly practical measures are needed beyond photos on bins,” he added.
“Can the Mayor now take tangible steps to address mortality of otters on Hartcliffe Way? This may include adjusting the grill on Pigeon House Stream in order that otters can pass under the road and otter fencing to prevent the passage of otters across the road,” he added.
"The Mayor is expected to respond to the formal question in the week before July’s full council meeting.
"When asked by Bristol Live about the screen, Bristol City Council said it was the Environment Agency's responsibility. "It is the Environment Agency who need contacting as it's not a flood risk or a highways issue," a spokesperson said.
"A spokesperson for the Environment Agency said the screen was not one of theirs. "Many culverted watercourses across Bristol rely on trash screens to prevent blockages which could jeopardise people and property due to flood risk," a spokesperson for the Environment Agency South West said. "This screen is not owned or used by us, but flood risk authorities who manage such assets are mindful of issues like this," they added."
Of course nothing happened. The shameful legacy of the Labour City Council and Mayor (the Green Party has an equal number of seats but appear disinterested). For around three years I have pushed to try to get wildlife over/underpasses at animal death black spots. The Mayor has decided to do what he always does "ignore it and it'll go away" and has ignored four emails and a letter detailing fox and badger as well as otter deaths on Bristol roads in 2023. But from a Council violating environmental law on a regular basis it should not be a surprise.
But in all of this time -otter deaths, wildlife safety passes or use of electrical devices to "deter" otters not one single word from the Greater Bristol Otter Group. And I would very much ;like them to get involved especially since I am the person most likely to have a dead otter reported to them. I have nothing against anyone at GBOG because, honestly, they have never been interested in getting in touch. I am interested in the wildlife and not ego boosting but I hope this explains and shows that I have always been open to cooperation and as naturalists that is what we should be doing.
