# What happens when a hedgehog story prickles its way into the BBC

*2026-05-22 — note*


[Silviu Petrovan](https://www.cambridgeconservation.org/about/people/dr-silviu-o-petrovan/) and I had quite a week appearing on [the BBC
website](https://www.bbc.co.uk/news/articles/c202g60qrlpo) and a dozen radio
and TV shows talking about the applications of AI to [saving hedgehogs](https://anil.recoil.org/ideas/hedgehog-mapping).
I thought I'd jot down a "behind the scenes" so other academics get a sense
of what to expect when a research story hits the national news cycle. Mostly,
make sure you have a clear couple of days to deal with live media appearances
with just a few hours notice and don't wear a rumpled shirt to the office\!

## Being interviewed by the beeb

Zoe Kleinman from the BBC pinged me after [hearing from Vultr](https://geotessera.org/blog/2026-03-30-training-and-inference-at-scale)
about the TESSERA v1 geospatial foundation model we've been developing here.  I grabbed [Silviu Petrovan](https://www.cambridgeconservation.org/about/people/dr-silviu-o-petrovan/) and [Kevin Cochrane](https://www.linkedin.com/in/kevincochrane) from
[Vultr](https://www.vultr.com) and we had a brisk 25-minute chat on Teams with Zoe and her producer.
This was all very stress-free and just like talking to anyone else, since it wasn't a live segment where every word had to be perfect.
Zoe published [the article on hedgehogs](https://www.bbc.co.uk/news/articles/c202g60qrlpo) later that day straight onto the BBC website.

<a href="https://www.bbc.co.uk/news/articles/c202g60qrlpo"> <figure class="image-center"><img src="/images/bbc-ss-hedgehogs-1.webp" alt="Every article on AI is improved with a cute hedgehog" title="Every article on AI is improved with a cute hedgehog" loading="lazy" srcset="/images/bbc-ss-hedgehogs-1.768.webp 768w, /images/bbc-ss-hedgehogs-1.640.webp 640w, /images/bbc-ss-hedgehogs-1.480.webp 480w, /images/bbc-ss-hedgehogs-1.320.webp 320w, /images/bbc-ss-hedgehogs-1.1600.webp 1600w, /images/bbc-ss-hedgehogs-1.1440.webp 1440w, /images/bbc-ss-hedgehogs-1.1280.webp 1280w, /images/bbc-ss-hedgehogs-1.1024.webp 1024w"><figcaption>Every article on AI is improved with a cute hedgehog</figcaption></figure> </a>

I hadn't realised before this just how widely read the BBC site is, as it has
over [95% of UK adults](https://www.bbc.co.uk/aboutthebbc/documents/ara-2023-24-our-audiences.pdf)
using it and [over half a billion unique visitors per month](https://www.bbc.com/mediacentre/2025/bbc-reaches-record-audience-digitally-annual-report-and-accounts).

> To be able to accurately identify the tiny creatures and other objects
> in image data, the Tessera system had to be trained on vast amounts
> of data — with around 20 petabytes, or the equivalent of 10 billion
> standard digital photos, used to build it.
> 
> After reaching the limits
> of the computing power allocated to the university, researchers
> installed additional processors under their desks to keep the
> process going.
> <cite>\-- [Zoe Kleinman, BBC News, May 2026](https://www.bbc.co.uk/news/articles/c202g60qrlpo)</cite>

I chortled when reading that last paragraph about 'under their desks' as I'd mentioned that over dinner to Zoe back at the [OpenUK AI Impact Summit roundtable](https://anil.recoil.org/notes/path-to-uk-india-ai-summit) a few months ago that [Amanda Brock](https://amandabrock.com/) invited me to. The jury-rigging is, for the record, entirely true, since we've had to cobble
together a [gigantic storage cluster](https://www.tunbury.org/2026/03/27/ceph-expansion/)
which we've only recently been able to [move offsite](https://www.tunbury.org/2026/04/17/cephfs-to-s3/).

## Getting on BBC Radio Live and the Today programme

<div class="video-center"><iframe title="" width="100%" height="315px" src="https://crank.recoil.org/videos/embed/b8afc63b-5069-4b62-920f-ff4578ca5074" frameborder="0" allowfullscreen sandbox="allow-same-origin allow-scripts allow-popups allow-forms"></iframe></div>
As soon as the article went live, the [University comms
office](https://www.communications.cam.ac.uk/) started sending in requests for
interviews from TV and radio producers all over the UK\!

- 06:30 BBC Radio 5 Live with Rachel Burden and Gordon Smart
  ([local clip](https://crank.recoil.org/w/dXoLNzkAsi7dPjWvfm6RTk) or [on BBC Sounds](https://www.bbc.co.uk/sounds/play/m002wj4t)).
  I was soaked to the bone after my morning run, and took this one with my teeth chattering, not realising it was to such a massive audience.
- Mid-morning on the [BBC Today programme](https://www.bbc.co.uk/programmes/b006qj9z)
  replayed the interview and also a [recorded piece from Zoe](https://crank.recoil.org/w/fRCL5vZZMEoP4MyKVsjg5P?start=9m09s) which is when the real phone-buzzing started. Silviu got his "digihog" term out there, and suddenly every regional radio producer with a slot to fill wanted to hear more.
- BBC Nottingham then held a longer slot with
  [Dino](https://www.bbc.co.uk/programmes/p0gp4k1y) where both Silviu and I came back on
  for two segments ([clip](https://crank.recoil.org/w/fRCL5vZZMEoP4MyKVsjg5P)), and also got a chance to talk about how the hedgehog tracking [started at Nottingham Trent Uni with Lauren Moore](https://theconversation.com/profiles/lauren-moore-1055140) who published [the first studies](https://doi.org/10.3390/ani10091523). I also had to nip into BBC Radio Scotland where we discussed [hedgerow reconstruction](https://www.nffn.org.uk/resources/bringing-hedgerows-back-practical-approaches-from-scotlands-nature-friendly-farmers) in Scotland briefly, and a few other drivetime slots where [hedgehog highways](https://theconversation.com/hedgehog-highways-what-are-they-and-how-to-help-build-one-177785) came up along the way.
- BBC Cambridgeshire ([clip](https://crank.recoil.org/w/oNK21tbXZ4s9dq37ukfHyh)) then did a brilliantly random hybrid video/radio piece with Louise Hulland where I got to talk about the [CCI common room](https://www.cambridgeconservation.org/about/the-david-attenborough-building/) where eavesdropping on random conversations is endless fun (and where I got to [hold wombat poo](https://www.science.org/content/article/how-do-wombats-poop-cubes-scientists-get-bottom-mystery) over coffee).

The way these radio sessions work is that a researcher gives you a call ahead of
the live slot, checks audio *(tip: don't use Airpods as they sound echo-y, just
speak normally into the phone handset instead)*, and then gives you a time for
the live slot when they'll phone (over Facetime in my case as I have an
iPhone).

When the call comes in, your audio is mixed in with the radio show running in
the background (but muted), and then before you know it you're live on national
radio with millions of listeners talking to the presenter! They only call a few
minutes before, presumably so that you don't get too nervous thinking about it
all.

## Doing TV slots on BBC and ITV

After this, the TV crews showed up to Cambridge to film pieces for television.
Since it's exam term and College is in a [quiet period](https://www.pem.cam.ac.uk/current-students/policies-procedures-guidance/college-regulations)
we couldn't film onsite as we've done [in the past](https://anil.recoil.org/notes/cacm-docker-cover) and so
used my office. They show up with a fairly portable set of camera and sound
equipment and lugged it up the three floors to my office.

<figure class="image-center"><img src="/images/bbc-le-hedgehog-1.webp" alt="David Coomes in the hotseat with BBC Look East" title="David Coomes in the hotseat with BBC Look East" loading="lazy" srcset="/images/bbc-le-hedgehog-1.768.webp 768w, /images/bbc-le-hedgehog-1.640.webp 640w, /images/bbc-le-hedgehog-1.480.webp 480w, /images/bbc-le-hedgehog-1.3840.webp 3840w, /images/bbc-le-hedgehog-1.320.webp 320w, /images/bbc-le-hedgehog-1.2560.webp 2560w, /images/bbc-le-hedgehog-1.1920.webp 1920w, /images/bbc-le-hedgehog-1.1600.webp 1600w, /images/bbc-le-hedgehog-1.1440.webp 1440w, /images/bbc-le-hedgehog-1.1280.webp 1280w, /images/bbc-le-hedgehog-1.1024.webp 1024w"><figcaption>David Coomes in the hotseat with BBC Look East</figcaption></figure>

The first [TV slot](https://crank.recoil.org/w/dxXkfLYocHMbZtdkZLAc8R) was from BBC Look East, and I grabbed [David Coomes](https://coomeslab.org) and [Sadiq Jaffer](https://toao.com)
at short notice from across the road to get some more team voices
included.

Having my overgrown plant-filled office did seem like quite a nice idea on paper, but
I think it came out less well when actually on TV since it's zoomed in and
the light isn't even.
I also hadn't reckoned on the sneaky 'reverse' shots the
cameraman took which exposed the completely disorganised other half of my
office away from the nice curated end\!

<div class="video-center"><iframe title="" width="100%" height="315px" src="https://crank.recoil.org/videos/embed/65a3d201-5a4d-439b-b7f0-0a9e6d5cd4c3" frameborder="0" allowfullscreen sandbox="allow-same-origin allow-scripts allow-popups allow-forms"></iframe></div>

We had about 30 minutes with the production team as well for this video,
since they also doubled as the camera crew. We discussed what shots to take, and they
did capture some gorgeous interactive views of the [TZE Explorer](https://tze.geotessera.org)
which you can see in the clip above (and I love the studio intro which zooms in on the [parametric UMAP false colour TESSERA map](https://www.cl.cam.ac.uk/~avsm2/cb2-pumap.svg) of Cambridgeshire).

ITV turned up later with another very patient cameraman to do a ["down the
line" piece](https://crank.recoil.org/w/u34bg5FqQQ7618hN2DpsKe), which was a
quite different structure from the previous one.  The presenters were all in
the recording studio remotely, and I got wired in with an earpiece to listen in
to them. The filming then happened as if I was in their studio, with
compositing to make it all work.

<div class="video-center"><iframe title="" width="100%" height="315px" src="https://crank.recoil.org/videos/embed/e30953ee-19ea-4fdc-8b06-36fcb5a5a47b" frameborder="0" allowfullscreen sandbox="allow-same-origin allow-scripts allow-popups allow-forms"></iframe></div>

The other thing to know is that the university comms office is actually
monitoring the media mentions of the University on an ongoing basis, since
Cambridge regularly goes viral with some mention in the news almost every day.

<figure class="image-right-float"><img src="/images/tveyes-ss-1.webp" alt="" title="" loading="lazy" srcset="/images/tveyes-ss-1.768.webp 768w, /images/tveyes-ss-1.640.webp 640w, /images/tveyes-ss-1.480.webp 480w, /images/tveyes-ss-1.320.webp 320w, /images/tveyes-ss-1.1920.webp 1920w, /images/tveyes-ss-1.1600.webp 1600w, /images/tveyes-ss-1.1440.webp 1440w, /images/tveyes-ss-1.1280.webp 1280w, /images/tveyes-ss-1.1024.webp 1024w"><figcaption></figcaption></figure>
The team sent me a weekly recap of all the mentions, including an interesting
service called [TVEyes](https://tveyes.com) who they pull clips of every mention across
the BBC, ITV, Sky and the regional stations and forward them on. This is the
only way I have any idea of knowing what actually went out in several cases since
rebroadcasting a story is quite common.

## Reflections

The thing I was most worried about, going in, was the
science communication standard required for a national audience, especially
since [climate change messaging](https://doi.org/10.1080/1533015X.2026.2628164)
is under such threat at the moment. Biodiversity, however, seems to trigger
a different (and perhaps more instinctual) response in people, and there
was no one _denying_ that there exists a [crisis](https://anil.recoil.org/papers/2025-biodiversity-9recs) in biodiversity.

Instead, much of the online conversation was about differences in opinion about
how to solve the land use problem from conflicting solutions (like [should we
cull badgers](https://www.badgertrust.org.uk/post/badgers-and-hedgehogs-separating-fact-from-fiction-in-british-native-wildlife)
to save the hogs). This feels like an area where [TESSERA](https://anil.recoil.org/projects/tessera),
[Enki](https://anil.recoil.org/projects/enki) and [Conservation Evidence](https://anil.recoil.org/projects/ce) could all have a positive impact
by making facts about the planet more available, so I feel quite energised
about that\!

I was very lucky that my collaborators (esp. [Silviu Petrovan](https://www.cambridgeconservation.org/about/people/dr-silviu-o-petrovan/)) in conservation
are old hands at this sort of thing, and they kept the focus on the
core conservation message which is the thing most of interest to a
national audience.

I also think I spent a bit too long talking about the innards
of [TESSERA](https://anil.recoil.org/projects/tessera), and need to practise a few snappy lines about
what it is at its essence. For example, [Sadiq Jaffer](https://toao.com) came up with the
term 'satellite fingerprint' to describe a TESSERA 10m tile, which seems hella
snappier than '128-dimensional embedding of Sentinel 1 and 2' when doing
an elevator pitch.

All in all, I very much enjoyed the experience. It has completely
disrupted my already packed work-week, but I must have received a hundred
messages from friends who otherwise couldn't care less about my
day-to-day research, and it gave the [project](https://geotessera.org/blog/2026-05-19-tessera-hedgehogs_1), [department](https://www.cst.cam.ac.uk/news/tessera-ai-model-helping-protect-hedgehogs-space)
and [College](https://www.instagram.com/p/DYnL2pTDkkb/) something to post about
that doesn't involve obscure functional programming! Thank you
Zoe Kleinman for taking the time to run this piece\!
