Good wildlife spotting everyone!
With everyone staying close to home, this year the wildlife spotting for the City Nature Challenge has been really urban. If you have more images taken over the weekend, you can still upload them now into iNaturalist and your sighting will be added into the count. Otherwise, it’s time to try and identify all those finds! Let’s see how many we can push to be research grade records.
I suspect we’ve had far more pavement weeds this year than we did last year. Certainly, last year the top three organisms recorded where blackbirds, harlequin ladybirds and wood pigeons. So far this year, our top three are cuckooflowers, Herb Robert and dandelions. Of course, although the weekend of wildlife spotting is over, we’ve now got time to make sure as many records as possible are properly identified, so that list could change.
Happily, although everyone was limited to gardens and short walks, the weather was much kinder than last year allowing us to really enjoy our local wildlife. There have been plenty of bee and butterfly garden visitors and the occasional bird to watch as well as all the plants. If you have enjoyed a weekend of wildlife recording, check out Greater Manchester’s Local Record’s Centre so that you can continue putting nature on the map. There’s also advice from the Wildlife Trust for Lancashire, Manchester and North Merseyside on how to improve your garden for wildlife.

The City Nature Challenge weekend has been popular across the country with over 4,000 people taking part and just under 60,000 observations made. If know of a city or region that would want to take part next year, then get in touch with the organisers. The City Nature Challenge was invented and is managed by the Natural History Museum of Los Angeles County and California Academy of Sciences: https://citynaturechallenge.org/
Graphene’s high-rise meadow

Back in June, perhaps some of the Graphene Week 2015 attendees spotted this little patch of wildness on the roof of the National Graphene Institute at the University of Manchester. This green roof was installed as the building was nearing completion in 2014 and is part of the commitment to improving the University’s campus as a habitat for wildlife. The University’s green roof policy can be found here, along with the other University policies about environmental sustainability.

Ahead of Graphene Week, the Biodiversity Working Group put together some information about pollinators, their requirements and the urban environment in order to have a sign in place for the delegates to read. This roof is particularly designed to attract bees, both wild bees and the honey bees from hives on roofs of the Manchester Museum and Whitworth Art Gallery.
The roof was created with a ‘sedum and wildflower’ mat made up with 21 different species. The low-growing sedums are now most visible around the sloping edges of the meadow, and taller species seem to dominate towards the middle. However, perhaps that’s not true; the sedums may be just hidden by the taller growing plants.

This summer, the Faculty of Life Sciences has arranged for a student to survey the roof to see how the plants are distributed. The Biodiversity Working Group will be continuing to monitor the roof’s progress to see how the composition of plants changes from this baseline. Some plants are likely to thrive, some will struggle and other’s will arrive as seeds blow over the roof or fall off people’s clothing.

Biodiversity on the road to Jodrell
Today the city centre-based members of the University’s Biodiversity Working Group hit the road to head out of the city and into Cheshire to hold a meeting at Jodrell Bank. Although home to the University of Manchester’s Centre for Astrophysics, the world famous Lovell telescope and a Discovery centre to explore the science of space, we were heading there to talk to Becky Burns, the Head of Gardens and Interpretation.
After all, it’s only fair that we should make the effort to visit Becky in her workplace from time to time instead of asking her to travel to us for meetings. The Biodiversity Working Group meets to discuss opportunities to increase the biodiversity on the campus of the University of Manchester and at about 35 acres, the Jodrell Bank arboretum is one of the University’s biodiversity hotspots. The arboretum holds two national Collections of Sorbus (whitebeam) and Malus (ornamental crab apples) trees, and with the late spring this year it is just about ready to burst into a profusion of blossom.
Visiting Jodrell wasn’t the only excitement of the day however, as this week the University was loaned a Nissan Leaf electric car and we were lucky enough to be allowed to use it to travel between sites. Qutie a number of Manchester’s buses are now hybrid diesel-electric, but this was my first experience of a fully electric car and it was pretty comfortable as well as having very green credentials. It was also just so quiet!
National Nest Box week
- What a lot of wood!
- RSBP sign
- Andrew Lawton
- Nearly ready…..
Yesterday, Andrew Lawton (the Museum’s curatorial trainee) and I braved the cold outside the Museum entranace to make bird boxes with Evan Powell from the RSPB.
For National Nest Box Week, we made homes for starlings and sparrows which will be placed in trees around the University of Manchester campus. We’re hoping to increase the amount of wildlife that calls the University campus home.
Members of the public helped us by decorating the boxes with their individual artworks
We couldn’t decide whether this was a colder event than the Wonderful Whitworth Wildlife bioblitz last year!
Tomorrow, artist Lucy Burscough will be making beautiful bird houses made from woven naural fibres in one of our Urban Naturalist events. These nesting pouches would be suitable for wrens and are inspired by the work of the Scottish ‘outsider artist’ Angus McPhee.
Safely stored?
Following an enquiry, I’ve looked out some thought-provoking specimens this week. I spent a quite melancholy afternoon searching our database with plant names listed as extinct or extinct in the wild in the IUCN Red List of Threatened Species. Here are a few of them:

Bromus interruptus (interrupted brome) was an agricultural weed found in southern and eastern England, but it became extinct as agricultural practices changed. The species is thought to have originated in Britain in the 19th century, but it was no longer found growing wild by 1972. However, this species is counted as extinct in the wild as seeds were collected from the last population and were cultivated in botanic gardens. Subsequently it has been re-introduced to the english countryside in the hope that it can re-establish itself.


This pretty red seaweed, however, is thought to be fully extinct. Vanvoorstia bennettiana (Bennett’s seaweed) has only been collected twice, once in 1855 and again 1886 from two different locations in and around Sydney Harbour. Despite extensive searches, this species seems to be extinct, perhaps because of disturbance and pollution of its habitat.


Finally, this is Melicope cruciata (cross bearing pelea), a tree in the citrus family which only ever grew on the Hawaiian island of Kauai. Rather poignantly, these seeds have been labelled and stored since their collection in 1895. This week, scientists from Russia have reported that the have successfully regenerated plants from 33,000 year-old seeds of Silene stenophylla which were found buried in the Siberian permafrost. However, I imagine that our cross-bearing pelea seeds have experienced much more variable conditions over their 117 year storage and are unlikely to still be viable.
