My study area within Colliery Dam Park is composed of five blocks (A, B, C, D, and E) fragmented by paths. Within each block I sampled five replicates for a total of 25. Each replicate was a point radius of 5 m in which I determined how many trees did or did not have English ivy growing on them.
Since the blocks are different sizes, I was unsure if larger blocks should have had more replicates to accurately scale the replicates to block area. Additionally, the varying block size made it so that I had to generate new random numbers to determine replicate locations. For small blocks I would walk too far out of the study area.
Blocks C and D had the most similar distribution while Blocks A and B had the most dissimilar distribution of trees with vs without ivy. This is interesting because both sets of blocks are located next to one another.
Hi There,
I came across this post, looking for other information on the park and am very interested in your findings.
I am one of the recreation coordinators of the city focusing on environmental stewardship and identifying number of trees with IVY in our parks and comparing how many trees we can actually “free” from ivy is a project I am interested in.
Please contact me as to where I might find more data on locations you might have collected from.
thanks
