Blog post #3 Ecological Survey of 92nd Street Park


For my ecological survey of a local population I visisted 92nd street park. The some of the characterstics of the area are that it had some slopes, was very grassy, there was many small flowers and weeds, ponds with algai and a variety of plants, lots of bushes and trees, some dead bushes, mostly native vegatation in the area, some introduced bushes and trees, squirrels, dragonflies, bugs, frogs. The organism that I chose to record was an English Daisy (Bellis perennis). It appeared on average of .34 times across the site. In the beginning of the the transect there was more of the organism and they were more clustered but towards the end of it there weren't any. The beginning of the transect was close to the water so that could be why there where more. I do think the transect seems representative of the site because the terrain was pretty much the same throughout. Overall, there weren't many challenges while sampling the site, however, I will say I did get a weird look here and there. The sampling showed me that the organisms are distbuted more close to the water. I would say that it is one population of the organisms in that area. Something that I noticed about this activity is that it seems to be a pretty controlled technique and because of that I think it is a usueful way to asses species distibution and population.

  1. Why do you think that water influenced their distribution? Would you expect the same if we had more rain? How would that influence distribution?
