Luquillo Canopy Trimming Experiment

International Institute of Tropical Forestry
Principal Investigator(s): 
Grizelle Gonzalez

Hurricanes are important drivers of periodic disturbances on tropical forests of the Luquillo Mountains, and this type of disturbance is expected to increase with climate change. This long-term experiment is designed to: 1) examine the effect of canopy disturbance (e.g., increasing light levels, temperature, moisture, etc.) vs. increased detrital inputs on rates of germination, growth, survival, detritus processing, nutrient cycling, soil conditions, and trophic structure, and 2) to increase the frequency of simulated hurricane effects above background levels to once every six to ten years.

Watershed Erosion Prediction Project (WEPP)

Overview & Applicability

The Water Erosion Prediction Project (WEPP), is a physically-based soil erosion prediction technology. WEPP has a number of customized interfaces developed for common applications such as roads, managed forests, forests following wildfire, and rangelands. It also has a large database of cropland soils and vegetation scenarios. The WEPP model is a distributed parameter, continuous simulation model, and is able to describe a given erosion concern in great detail for an experienced user.


The WEPP model consists of multiple applications that can estimate erosion and sediment processes on hillslopes and small watersheds, taking into account climate, land use, site disturbances, vegetation, and soil properties.

Scenarios Network for Alaska and Arctic Planning (SNAP)

Overview & Applicability

SNAP provides several platforms for looking at historic climate trends and climate projections in Alaska and western Canada:

1. Downloadable datasets for historic climate data and projected climate data (temperature and precipitation).

2. Interactive map - provides climate projections for Alaska and western Canada for each decade through 2100. User can choose what variables, time periods, seasonal averages, and emissions scenarios they’d like to view.

Scenarios Network for Alaska and Arctic Planning (SNAP) climate projection map

SNAP provides climate projections (temperature and precipitation) for Alaska and western Canada, using an ensemble of climate models (GCMs) and 3 emissions scenarios. Information is presented in a variety of formats.

Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation (SREX)

This special report of the IPCC examines the scientific literature on the relationship between climate change and extreme weather and climate events ("˜climate extremes"), and the implications of these events for society and sustainable development.
