2017 Summer Plant Census

by

Twice a year the Portal crew gets a little larger, and spends a few extra days, and we count plants on all 384 quadrats. Despite some of us being in our second decade of visiting the site, and everyone on the plant crew being intimately familiar with most of the species at the site, and that the rodent RA has been watching the plants grow and giving us monthly updates, we still never really know what we’re going to find once we get out there. The desert does what it wants.

The uncertainty seems especially high for the summer plant community. Some years we arrive to an ocean of grass, waving in the breeze. Those are the years we spend a lot of ‘quality time’ with each quadrat. Other years we arrive to a dustbowl. We walk around the site laying our PVC quadrat down and picking it back up again and saying ‘zero’ 384 times. [Okay, we don’t really ever get all zeros. But it feels like that when you’re out there.] And some years we show up to find some new arrivals, species that finally decided to show up after 40 years. Then we spend less time counting individual blades of grass, and more time pouring over our regional species list and plant ID guides.

Summer 2015, ‘Who are you and where did you come from?’

 

This summer was pretty good for forb diversity. Forb species like Dalea, Cassia, Kallstroemia, Ipomea and Sida were relatively abundant.

In the summer we also measure shrub cover on the plots, so we get some bonus quality time with the plants.

 

There are lots of other bonuses to the summer plant census that make up for the brain-melting heat. As we’re walking around the plots, we get to see snakes (Mojave rattler, Common king snake, gopher snake, coachwhip, and Coral snake on this trip), horned lizards, turtles, tarantulas and exceptional insect diversity that are not out and about from October to May.

    Reblogged this on Jabberwocky Ecology and commented:

    Someone (**cough** **cough** Morgan) fell down on their job rebloging the Portal Project 40th anniversary posts to Jabberwocky. But that means this week is the week o’ Portal as we reblog the various posts from the past few weeks. First up, what happens when we go out in the summer to count plants?
