After hundreds of hours of collecting, sorting, identifying and photographing seashells, my comprehensive field guide 'Seashells of North Haven Beach' is finally out. Available now at it's a must have for Australian beachcombers (I promise!)

Photographed one of my mega bucket list species on a recent trip to Kakadu NP, Leichhardt's Grasshopper (Petasida ephippigera). Found only across the Top End of the NT, this species is declining. I waited almost 5 years to see one after failing to find one in March 2020

But discovery hasn't finished! Since we ran the numbers earlier this year, at least 50 new species (mostly introduced) have already been found for Royal, with a smaller handful for Yosemite. There's still lots to discover, so head out there with your camera and plant press!.

Second, the most complete picture of the plant biodiversity from each park relied on combining all three data streams: each had unique species that the other two didn't. Excitingly, @inaturalist records contributed 63 new species for Royal, and 20 for Yosemite

Key take homes?. First, compiling species lists for a reserve requires lots of manual curation! We found many errors, including misIDs, wrong coordinates, taxonomic issues, and databasing errors. These result in differences of 100s of species across curated vs non-curated lists.

And what about Yosemite? It reached 1,632 species, including 1,409 natives, in an area of 300,000 ha.

How many vascular plant species do you think are in Royal NP? We compiled a total of 1,414 species! This includes 1,146 natives, more than the entire British Isles in an area of just 15,000 ha.

New paper: We compiled master plant species lists for 2 of the 5 oldest national parks: Royal (Australia) and Yosemite (USA) by combining herbarium vouchers + @inaturalist records + official expert park lists, extensively manually curating all records.

@royalsocnsw @inaturalist @will_cornwell @hsauquet_bgsyd a = Acacia diminuta, WA.b = Wurmbea dilatata, WA.c = Morelotia microcarpa, WA (pic by Nick Lambert).d = Philotheca cymbiformis, WA (pic by Greg Tasney).e = Dodonaea ericoides, WA.f = Maireana microcarpa, NSW.g = Bertya oblonga, NSW.

New paper in @royalsocnsw: 2 years after our online photographic census of Australia's flora, +800 'unphotographed' species now have images on @inaturalist! Huge thanks to all observers (incl. dipping into old hard drives!) + experts IDing these images

Master species list for Wategora Reserve in western Sydney now published; I recorded 546 plant species (274 native) in 20 ha urban reserve from 300+ survey hours (2020-2023). Combined with historical surveys (1976-1992), total 727 species. Check it out:

Check out for all Australian records of myrtle rust on iNaturalist, plus some fantastic journal posts written by @_Alyssa_Martino helping to explain the science behind the fungus, and how citizen science is crucial for documenting its distribution.

We need your help recording #MyrtleRust across Australia to track its spread. Hop onto @inaturalist, join Gum Tree Guardians, and upload your pics! All data feed into @atlaslivingaust for researchers to use. More info here: @DavidPocock @_Alyssa_Martino.
