In a pollen supplementation experiment, fruit or seed production by flowers exposed to natural pollination is compared to that following hand pollination either by pollen supplementation (i.e. manual outcross pollen addition without bagging) or manual...

For many species and seed sources used in restoration activities, specific seed germination
requirements are often unknown. Because seed dormancy and germination traits can be
constrained by phylogenetic history, related species are often...

Recent studies have shown that the use of native plants by landscape architects and contractors in the southeastern United States has increased as has the clientele interest level in native plants. Recommendations to increase the use of native species...

Foresters and horticulturists should be aware of the risks of invasive species and should be updated on a regular basis regarding emerging pest threats. In the Pacific Northwest, many new potential threats to natural ...

This article profiles past and present deforestation and reforestation in the U.S. Virgin Islands, along with the geography and ecology of the three islands. The islands of St. Thomas and St. John form one ecological and cultural unit, whereas St....

Deploying well-adapted and ecologically appropriate plant materials is a core component of successful restoration projects. The USDA Forest Service has developed generalized provisional seed zones that can be applied to any plant species in the United...

Darrel Morrison discusses why he is intrigued by the value of linking ecology and ecological processes with art and music in the design of landscapes that might be considered “ecological art.” The products of ecological art have the potential to be,...

In the fragmented ecosystems where we live and work, the importance of diversity in our landscapes cannot be over emphasized. Diversity of native plants, insects, mammals, birds, amphibians…. They all play a crucial role in sustaining a healthy...
