Fall 2020 BioBlitz for Russ Pitman Park (species count)

by Eric Duran, Head Naturalist

Twice a year, the Nature Discovery Center has a BioBlitz, one in the Spring, and one in the Fall.

A bioblitz is a chance for an organization to count as many species of living things as they possibly can in a given area.

This helps us keep an eye on how populations of plants, fungi, animals, and slime molds are doing in our park (Russ Pitman Park) from year to year, as well as how living things may be faring in the Houston area. We’ll be able to understand long term trends as the years go on, and we continue to do them, as well.

A bioblitz is also a chance for our staff to better understand what’s living here in the park, and keep a detailed list of everything that may be living here (and is observable). For our naturalists and staff, its also a lot of fun!

This year’s Fall 2020 BioBlitz, just ended, and we’re happy to report the count here.

The final list is compiled, and the numbers are counted. This year we set the dates to 10/9 – 10/26, giving us a little over 2 weeks, because we had very little help with observations this year (Covid-19 being the reason).

I did most of the species observations this year, but we got help from retired Senior Naturalist Mary Ann Beauchemin, Mary Spolyar from the Native Plant Society and the Gulf Coast Master Naturalists, Office Manager Pam Dunker, naturalist and teacher Debbie Lancaster, and our community of resident birdwatchers.

This year, we counted 340 species over all, which broke down like this…

ANIMALS: (139 species)

VERTEBRATES: (50 species)

INVERTEBRATES: (89 species)

FUNGI: (36 species)

SLIME MOLDS: (1 species)

PLANTS: (164 species)

There’s nothing new and exciting to report this year, but we had a very good bird list for a Fall Bioblitz, and we identified a few small insects that hadn’t been listed in the park before. We ended up having a good insect and invertebrate count, because of the warm weather. Overall, we were up from last year’s Fall Bioblitz (our first Fall Bioblitz, as a matter of fact). We had several people helping us last year, but we actually got a higher number of species! (Last year we only had 281 species.)

Let’s hope that covid is more under control for the Spring Bioblitz 2021, which will be sometime in mid-late April.

PLANTS: (164)

There are of course way more than this number of plants in Russ Pitman Park.

The Nature Discovery Center, however, already has a rather voluminous and exhaustive plant list for the park. Thus, the naturalists who participate in our Bio-blitz do not attempt to document all or even most of the plants in the park. Participants simply noted plants they found interesting, observed fruiting or blooming, or thought may not already be on the official park list of plants.
