Title

Vegetation profile and canopy height of Tabonuco, Colorado and Cloud Forests
Summary

Short name: 

LUQMetadata21

Data set ID: 

21

Abstract: 

The overall height and the presence of vegetation in different height intervals above ground is recorded above points on a 5 x 5 m grid in three hectare-sized plots in the Luquillo Experimental Forest, Puerto Rico. One plots each is in tabonuco forest (350 m elevation), colorado forest (650 m) and cloud forest (1000 m). The first records were made shortly before Hurricane Hugo, in 1989. Post hurricane measurements have been made five time to six time in each plot, the most recent been in 1998 for all plots. The results show the damage to forest structure wreaked by Hurricane Hugo, steady recovery of forest structure after Hugo, minor damage by Hurricane Hortense in 1996, and resumption of recovery after Hortense. Maximum canopy height and the vertical distribution of vegetation in the forests are returning to pre-hurricane Hugo values.

Methodology

Methods: 

Vegetation heigh profile and canopy heights are being constructed from data taken on 5 x 5 m grid systems in the tabonuco forest (in the southwest corner of the 9 ha grid at El Verde), colorado forest (a couple of hundred meters from theshelter nearest the eastern end of the Tradewinds Trail), and in cloud forest (near the trail leading to the plane reck on the Pico del Oeste). The tabonuco grid is 1.08 ha, with 475 grid points; the others are one ha. each, with 451 grid points each. The presence or absence of vegetation (leaves or wood) within height intervals along vertical line above each point in the grid is recorded. Vegetation "hits" on the line are recorded with a pole held vertically and marked at 0.5 m intervals to 3.0 m. The height of the vegetation above 3.0 m is estimated, and checked with an "optical tapemeasure".
