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)

 Spatial 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

 Dataset Location:

 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). 

 Data Collected: Species, abundance
