Landscape-Scale Forest Dynamics in the Luquillo Experimental Forest in Puerto Rico 1936-1989
This study examined landscape-scale forest dynamics in the Luquillo Experimental Forest (Puerto Rico). The analysis was based on vegetation maps created from aerial photographs taken in 1936 and 1989. For details on methods and results, please see the published paper (Foster, D. R., M. Fluet and E. R. Boose. 1999. Human or natural disturbance: landscape-scale dynamics of the tropical forests of Puerto Rico. Ecological Applications 9: 555-572). The Abstract from the paper is reproduced below. "Increasingly ecologists are recognizing that human disturbance has played an important role in tropical forest history and that many assumptions concerning the relative importance of natural processes warrant re-examination. To assess the historical role of broad-scale human versus natural disturbance on an intensively studied tropical forest we undertook a landscape-level analysis of forest dynamics in the Luquillo Experimental Forest (LEF; 10,871 ha) in eastern Puerto Rico. Using aerial photographs (1936 and 1989), GIS, a model of topographic exposure to hurricane winds, and historical data, we sought to: (1) document historical changes in extent, cover and type of forest vegetation, (2) evaluate the distribution of land-use and hurricane impacts, (3) assess the contributions of these processes in controlling current vegetation patterns, and (4) relate these results to ongoing ecological, conservation and natural resource discussions. "With over 1000 m of relief in the LEF, the broad vegetation zones of Tabonuco (below 600 m a.s.l.), Colorado (600-900 m), Dwarf (above 900 m), and Palm forest are determined by environmental gradients. However, over the past 60-100 years forest extent, cover, and type have been transformed: in 1936, 40% of the LEF was unforested or secondary forest and less than 50% had continuous canopy (more than 80% cover); in 1989, less than 97% was continuous forest. Secondary forest and agricultural lands in 1936 were replaced largely by Tabonuco and Colo
Litterfall in tabonuco (subtropical wet) forest in the Luquillo Experimental Forest, Puerto Rico (MRCE Litterfall data)

Long-Term Elevation Plots (LTEP) (Altitudinal transects vegetation data along three rivers in the Luquillo Experimental Forest)
The composition of plant communities changes with elevation in the Luquillo Experimental Forest (LEF). The goal of this project is to document the patterns of these changes, and in particular, to determine whether the distributions of individual species are independent of one another, or whether they are related, in either a congruent or a hierarchical manner. Thirty-two permanent vegetation plots, each 50m by 20m are being established in the LEF, with 5 plots along the Icacos river, 11 along the Mamayes river and 16 along the Sonadora stream. The plots were established at every 100m in elevation, starting at 200m above sea level. All woody, free-standing stems greater than 1cm dbh were marked, identified and mapped into 5x5 subquadrats. We anticipated that gradient analysis will show whether the distributions of species are coincident or independent, enabling us to evaluate whether separate, genuine plant communities exist in the LEF. Because the plots are permanent, we also expected that they allow us to better evaluate how different vegetation types, at different elevations, respond to large scale disturbances, especially hurricanes.

Bird abundance-mist nets in the Luquillo Forest Dynamics Plot and Nora Devoe Cut Plots in the Luquillos Experimental Forest
This project seeks to measure long-term trends and variability in bird populations in tabonuco forest at El Verde. Repeated measures of bird populations using mist nets are conducted annually in the Luquillo Forest Dynamics Plot. For each bird caught, I obtain physical measurements (weight, length of wing, length of tail), and estimates of fat, age, and breeding condition. Captured birds are marked to estimate mortality and longevity. Data on canopy openness are also collected annually at each mist net as part of this project.

Revegetation of landslides, vegetation > 1.0m (Large landslide plots at the Luquillo Experimental Forest)
Here we use permanent plot data sampled from 16 landslide to documents temporal successional pathways in landslide patches (without the use of a chronosequence, cf. Guariguata 1990) and address the following questions: (1) What are the successional pathways of landslide and what species define them? How much pathway variation of individual plots is there within these landslides? (2) How similar are pathways among landslide? Is there any evidence that, with time, landslides either converge to a common vegetative enpoint or slow in the rate of successional change? The purpose of this study is to document the recovery of vegetation on new landslides in the Luquillo Experimental Forest.

Fern leaf traits observation at the Luquillo Experimental Forest (LEF)
Ferns are a common element of the understory of forests, yet little is known about the dynamics of leaf production. The long-term role of an individual fern in the ecosystem understory is a function of the number and size of leaves produced over time and the quality of those leaves. Selected functional plant traits (see also LUQ186 -Fern nutrients) were measured in order to supplement non-destructive measurements and detect patterns of primary productivity of ferns in the long-term studies at the Luquillo forest where ferns have been included (eg. Fern growth and demography (LUQ75), Canopy Trimming Experiment (LUQ143 and LUQ146) and the Luquillo Forest Dynamics Plot). Among the important characteristics of fern leaves in the forest understory are the area and biomass of leaves needed to calculate specific leaf area (SLA), leaf dry-matter content (LDMC) and leaf shrinkage. Therefore a large sample of whole leaves and leaf material from several species in the Luquillo Experimental Forest understory was collected, weighed and leaf area measured. The means and regression relationships among these functional traits for species, leaf type and leaf size can then be used to estimate leaf production and turnover rates in temporal studies of fern growth.

Fern sporophyte growth observation at the Luquillo Experimental Forest (LEF)
Long-term (20-year) monitoring sites have been established in the Luquillo Experimental Forest. Individuals of approximately 20 species of ferns are being monitored on a regular basis to determine plant life history classes, leaf production rates, fertility characteristics and leaf damage levels. Effects of natural disturbance will be interpreted in light of these parameters. The study includes sites at El Verde, and Espiritu Santo and Bisley watersheds. A comparative study of ferns in the mangrove community at the Jobos Bay National Estuarine Research Reserve was started in January 1998 and completed in January 2001. Comparisons of similar species will also be made at temperate sites. Data file FERNGROWTH contains data, on a line-line basis, about individual leaves. Information in this file includes measurements and observations as well as leaf location and identification information. Leaves in this file was monitored three times a year from the time the plant was first included in the study until the plant died, disappeared, or was dropped from the study. The same information was collected on leaves used in defoliation experiments (FERNDEFO). Annual measurements of leaf counts and longest leaf measurements on selected species from 2001 through 2010 are included in FERNPH02. Other files in the data set includes a file of supporting information on characteristics the plants on which leaf observations were made (FERNSEQ), additional field observations about the leaves, plants and sites (FERNFLD) and details about monitoring dates (FERNDATES).

Luquillo Experimental Forest Canopy Trimming Experiment CTE2 2015-2020 30-minute abiotic data
The data archive is here: https://doi.org/10.2737/RDS-2021-0028 please use this DOI when citing this dataset. This data publication contains 30-minute values for abiotic field data from 3 treated and 3 control plots from the Canopy Trimming Experiment (CTE) located near El Verde Field Station in the Luquillo Experimental Forest (El Yunque National Forest), Puerto Rico collected from 2015 through 2020. In December of 2014 (CTE2), in 0.09 hectare (ha) square plots near the El Verde Field Station the forest canopy was trimmed and the canopy debris was littered to the forest floor. The plot size and trim amounts were based on the patch disturbance after the two most recent hurricanes before 2017, both category 3 hurricanes at the location of El Verde: Hugo in September 1989, and Georges in September 1998. Data were collected in the inner 0.04 ha quadrants of the 0.09 ha trimmed plots to minimize edge effects. Each plot was made up of 16 subplots with different data types collected in each subplot. There were 3 sets of control and treated plots, with each set near El Verde field station. Field data include 30-minute: solar radiation, soil profile volumetric water content, shallow soil volumetric water content, canopy leaf saturation, litter leaf saturation, air temperature, soil temperature, air relative humidity, vapor pressure, and throughfall. Field data were collected by one automatic sensor in each plot inside a designated subplot, except: soil profile volumetric water content, canopy leaf saturation, and litter leaf saturation; each were collected in three subplots.

Spatial Variation of Soil Carbon, Nitrogen and Phosphorus in the Luquillo Experimental Forest (LEF) (LEF_SOIL_CNP)
Hongqing Wang, a Ph.D graduate student of SUNY-ESF, with the help of many others, took soil samples in 119 locations over the entire Luquillo Experimental Forest (LEF) during the summer of 1998 and 1999. Soil organic carbon, total nitrogen and acid-extractable phosphorus were measured in the laboratory of SUNY-ESF; soil moisture and bulk density were measured at the laboratory of the El Verde Station of UPR. The geodetic coordinates (Lat., Lon.) and elevation of each sampling location were determined using a Global Positioning System (GPS Pathfinder Basic Receivers, Trimble Navigation Ltd.) in the field. Meanwhile, slope angle, aspect and topographic features (Ridge, slope I (<35 deg.), slope II (>=35 deg.), valleys) were also measured and observed in the field.
