City Nature Challenge 2020! April 24-27

Hi Everyone,

For the very first time, the Brighton & Lewes Downs Biosphere will be cometing in the international City Nature Challenge (now in its 5th year). It will take place from April 24th through to April 27th. We will be competing with 250 locations worldwide, including nine other UK cities (Birmingham & Black Country, Bristol & Bath, Glasgow, Lancashire, Liverpool City Region, London, Greater Manchester, Nottingham City, and North East England). You can see exactly who's participating this year & read more about the challenge at the City Nature Challenge website .

The timeline for the City Nature Challenge is:
April 24-27: Making observations. The project won't accept any observations made before 12:00am on April 24 or made after 11:59pm on April 27.
April 28 - May 3rd: Getting everything uploaded and identified! As long as the observations were made in the April 24-27 time frame, you can still upload them afterward. Also, the more observations we get identified to species, the higher our species count will be!
May 4: Results announced!

The "big 3" stats that we look at for the City Nature Challenge are (1) number of observations, (2) number of species, and (3) number of people who participated. This year we'll also be putting more emphasis on those numbers with verifiable (not captive/cultivated, and has media) observations.

Here's the Brighton & Hove Biosphere City Nature Challenge 2020 iNaturalist project

We're tagging you in this journal post because you're one of the top observers and/or identifiers in the Biosphere/Sussex area, and we'd love your help with the City Nature Challenge (CNC)! Any area within the Biosphere boundary is fair game for the CNC (terrestrial, freshwater, marine, rural, urban), and we need people out there making observations, finding species, and helping to ID the observations coming in. With local organisations we are also hoping to have a number of bioblitz/ID events being held within the Biosphere area during the CNC - we'll post these to the project and Nature2020 CNC webpage once they're confirmed. We'd particularly like people to visit sites that are of high biodiversity value in the Biosphere region and/or home to species characteristic of the region.

Here is a reminder of the Biosphere's boundary

Thanks in advance for your help with the City Nature Challenge! We hope the Biosphere has a great first year of the competition!

I'm originally from Kent, but I live in NYC these days, so I won't be making any UK observations. However, I am generally pretty good on mollusc IDs (land, freshwater, and marine), so feel free to ping me if and when you need mollusk IDs. :)

I live in Liverpool and will be doing the LIverpool City Nature Challenge. If I have put any records into to your area, it must have been when I have been visiting my daughter who lives in Horsham and having a 'day out' in your catchment area. Good luck!

Another international contributor, I live in Australia but put in some records when visiting relatives in Hastings so I won't be contributing directly but will try to get the rellies to make an effort!

Apologies, I must have been on holiday. I'm not really in the catchment for any of the cities this year, but I will do my best identifying for all of you.
