Data from: Size-related scaling of tree form and function in a mixed-age forest
Many morphological, physiological and ecological traits of trees scale with diameter, shaping the structure and function of forest ecosystems. Understanding the mechanistic basis for such scaling relationships is key to understanding forests globally and their role in Earth's changing climate system
Data from: Spatiotemporal fire dynamics in mixed-conifer and aspen forests in the San Juan Mountains of southwestern Colorado, USA
Mixed-severity fire regimes may be the most extensive yet poorly understood fire regimes of western North America. Understanding their long-term spatiotemporal dynamics is central to debates regarding altered fire regimes and the need for restoration in the context of changing climate and nearly a c

Data from: Tropical trees in a wind-exposed island ecosystem: height-diameter allometry and size at onset of maturity
1. Tropical tree species adapted to high wind environments might be expected to differ systematically in terms of stem allometry and life-history patterns, as compared with species found in less windy forests. We quantified height-diameter (H-D) allometries and relative size at onset of maturity (RS
Data from: Interspecific functional convergence and divergence and intraspecific negative density dependence underlie the seed-to-seedling transition in tropical trees
The seed-to-seedling transition constitutes a critical bottleneck in the life history of plants and represents a major determinant of species composition and abundance. However, we have surprisingly little knowledge regarding the forces driving this ontogenetic transition. Here we utilize informatio
Data from: Determinants of flammability in savanna grass species
1. Tropical grasses fuel the majority of fires on Earth. In fire-prone landscapes, enhanced flammability may be adaptive for grasses via the maintenance of an open canopy and an increase in spatiotemporal opportunities for recruitment and regeneration. In addition, by burning intensely but briefly,
Data from: Radial changes in wood specific gravity of tropical trees: inter- and intra-specific variation during secondary succession
Variation in wood specific gravity (WSG) within and across species of tropical trees is poorly studied in relation to vegetation change during tropical forest succession. We investigated WSG of 91 species in eight long-term plots along a successional chronosequence in northeastern Costa Rica. Radial
Data from: Pinus ponderosa alters nitrogen dynamics and diminishes the climate footprint in natural ecosystems of Patagonia
1. Evaluating climate effects on plant-soil interactions in terrestrial ecosystems remains challenging due to the fact that floristic composition co-varies with climate, particularly along rainfall gradients. It is difficult to separate effects of precipitation per se from those mediated indirectly
Gunnison National Forest Timber Management Plan
The plan objective is to provide continued direction in managment and _. administration of timber resources. The plan is a functional expansion of the Forest Multiple Use Plan. The actions and objectives of the plan are coordinated with other resources of the Forest through an Environ- mental Impact

These overlays are to be used with the available Ue. S- Forest Service overlay map set prepared for ; the draft Model Transportation Plan

Initial partial cutting in old-growth spruce-fir /
Interim guidelines are provided to aid the forest manager in developing alternatives to clearcutting in old-growth spruce-fir forests in Colorado and southern Wyoming. Included are partial cutting practices for different stand conditions and windfall and insect susceptibility that should maintain co
