Overview:
El Verde Grid Invertebrate Data is a long-term observational study of the snail community at the Luquillo LTER on Puerto Rico.
Ecological Level: Community
Biome: Tropical
Location: Puerto Rico (18 deg 10' N, 65 deg 30' W)

Scale of
data: The Luquillo Forest Dynamics Plot is a 16 ha grid
and snail data is collected at 40- 25m radius sampling sites on this
grid.
Timespan: 1991-2007, but pre-1995 there is a different sampling intensity than post-1995 and affect abundance estimates (see Issues below)
Frequency: 2 times per year (wet season and dry season)
Observational/Experimental: Observational

Data
collection summary:2 times per year, the Luquillo Forest
Dynamics Plot is surveyed for snails. Surveys are conducted at 40
permanently located points on the plot. A single observer records for 10
minutes all birds detected within 25 m radius, (though there are
additional files available recording data on birds observed > 25 m
from the observer, if desired).
