The Urban Forest Project Protocol, one of many protocols developed by the Climate Action Reserve, seeks to increase carbon storage by urban trees and quantify how tree planting, maintenance, and improved management activities reduce greenhouse gases. The Protocol provides detailed guidance to ensure that tree projects meet eligibility requirements, produce …

Plant populations may naturally adjust to climate change in three ways:
1. Altered physiology and development
- Altered physiology and development in response to environmental change can occur in some plants. One example of this is environmental preconditioning. In such cases, prior exposure to water stress can induce physiological changes (osmotic adjustment) that ameliorate the

Urban trees play multiple roles when it comes to local air pollution. While trees in general help reduce air pollution, including absorbing the greenhouse gas carbon dioxide, some species contribute to local smog by emitting volatile organic carbons (VOCs). Planting locations of individual trees and species selection make a difference in the overall pollution balance.
Many urban trees help clear the air of pollution, although some are better at it than others (Table …

The mountain pine beetle (Dendroctonus ponderosae) (Fig. 1) is an indigenous North American bark beetle that has been confined to the western part of the continent by the Rocky Mountains and the Great Plains geographical barriers. Exactly one generation per year is ideal for this diapause-free, or dormancy-free, species.

While the biological processes of photosynthesis, respiration, and decomposition are similar for all forests, their relative importance differs by forest type and location. Some forests grow more rapidly, but dead …

Plant tissue (including wood) is composed of about half carbon, all of which comes from carbon dioxide (CO2) in the atmosphere. Photosynthesis rates tend to increase as CO2 levels rise, leading to an increase in dry weight, or biomass, of plants grown under elevated carbon dioxide levels.

As climate variability increases, each species within an ecological community will respond individually. With current information, it is impossible to know specifically how climatic changes will affect native plant populations or how invasive plants will respond. It is certain, however, that no two plants will respond in the same way to any given change. Regardless of the instigating factors, the establishment of invasive plants would likely be assisted if the current ecosystem breaks …

The gypsy moth (Lymantria dispar) (Fig. 1) was intentionally introduced from Europe to the northeastern United States in 1869. It has spread west and south in the United States as well as north into Canada, where it has reached its northern limit due, in part, to adverse climatic conditions. Currently, the gypsy moth is confined to areas east of Lake Superior, although isolated infestations …
