Hi All, I am planning on conducting a study where I exclude different seed dispersal vectors in order to identify herbaceous plant community assembly patterns. I am interested in excluding medium-small mammals, birds and wind -separately. I am having a bit of trouble figuring out how to exclude one of these vectors without 1) excluding the others (e.g. if I put up a fence to block mammals how do I still allow birds to enter the plot-aside from just leaving the top open); and 2) altering environmental conditions for the plant communities (e.g. shading them with the barriers). Does anyone have experience excluding ANY or all of these agents and can enlighten me? I appreciate any suggestions.
