Restoration and Climate Change? Society needs to invest in good forest management. In general, this means restoration of structure and composition to a point where ecological processes can proceed as they were meant to. Among these processes is the ability of the plants and animals in the ecosystem to express the variability in their genes that will enable them to adapt to a changing climate, an expression that is more difficult under existing conditions.

Restoration and Climate Change?

In the face of changing climate, if you want to roll with the punches, then a restored forest is the best way to go.

New Mexico Forest and Watershed Restoration Institute


What is forest restoration?

The re-creation of historic structure (principally through the removal of smalldiameter trees) in forests and woodlands, and maintenance of the structure and other ecological processes by reintroduction of an historic fire regime.

Studies show for Southwest ponderosa pine: • Trees were in groups • Groups were 0.1-0.7 acre in size • Space without trees separated groups • All sizes and ages were in the landscape See www.eri.nau.edu/en/the-ecological-restoration-process/ establishing-reference-conditions New Mexico Forest and Watershed Restoration Institute

Northern Goshawk – Accipiter gentilis

New Mexico Forest and Watershed Restoration Institute


NGH Guidelines not for Goshawks “Goshawk Guidelines� is a name for a method that restores ecological function to ponderosa pine stands. The resulting forest structure mimics the diversity of historic tree stands, allowing many natural processes to continue, and creates resiliency in the forest. It is not single-species management, or even wildlife habitat management.

Northern Goshawk guidelines These guidelines improve habitat for about eight prey species of the NGH. A group or clump consists of trees that are close enough together that a squirrel can travel from one to the other without having to go to the ground. True for all sets of guidelines.

Take-Home Message II: Summary To help ponderosa pine forests adapt: • Keep the largest trees and the smallest trees; • Remove 65-90% of the standing trees, leaving some in all diameters; • Leave tight groups of various sizes; • Leave openings – not just spaces between groups, but group-size areas with no or very young trees; • Burn it as soon as a low-intensity fire will carry through the area.

Key to 5 P-J Types 1a. Deep soils (>14 inches deep), surface generally free of large rock fragments or large amounts of gravel, and capable of producing continuous fine fuels under normal precipitation 2 1b. Shallow or transitional soils, surface may be eroded and often is rocky or droughty, and usually not capable of producing continuous fine fuels under normal precipitation – 3 2a. Most precipitation falls during summer. The oldest trees (possibly >150 years) are older and usually taller than those found in Grasslands – PJ Savanna or Juniper Savanna 2b. Season of greatest precipitation can vary. Old trees are very rare and found on microsites that historically would have allowed escape from fire – Grassland 3a. Generally on shallow, coarse-textured soils. Most precipitation falls during winter. Piñon and juniper are the dominant species – PJ Persistent Woodland 3b. Soil transitional between deep Savanna soils and shallow Persistent Woodland soils – 4 4a. Bi-modal precipitation pattern. Uneven-aged stands on rolling uplands with persistent, taller trees. Probably common historically, but rare under current conditions – PJ Open Woodland 4b. Most precipitation falls during winter. Sagebrush or oak co-dominate with the P-J, but the shrub species may be crowded out under current conditions. This type often found in small patches that can be difficult to map on a statewide scale – PJ Shrub Woodland
