Nurse Trees

Nursery management, tree propagation and marketing: A training manual for smallholder farmers and nursery operators

Introduction

Published by ICRAF, this manual is intended to provide training support aimed at farmers and nursery operators to promote the propogation and establishment of small-scale nurseries. 

Goals & Methods

To achieve the aim of encouraging superior techniques and materials for superior planting, the document offers five modules. Each module covers a different step in the nursery establishment process, from sourcing and selecting seeds to establishing a nursery business.

Ecological Restoration of Coal Mine-Degraded Lands in Dry Tropical Climate: What has been done? And what needs to be done?

Background

This paper discusses known methodology for how to restore native forest to abandoned coal mines. The paper splits the process of reclaiming abandoned coal mines into two sections, 1.) physical, technical, or engineering restoration and 2.) Biological Restoration. It also stresses taking a landscape scale approach to restoration, which includes 1.) an initial survey of the area, 2.) determination of the ultimate landscape objectives, and after restoration landuse possibilities, 3.) preparation of working plans for each phase of the restoration operation.

Can Pinus Plantations Facilitate Reintroduction of Endangered Cloud Forest Species?

background

This study tested the hypothesis that pine plantations can simulate the conditions of early forest succession, acting as a habitat for other native or endangered species to establish. In the cloud forest region of central Mexico, some tree species have become endangered due to land use change for both livestock production and tree plantations.

A Place for Alien Species in Ecosystem Restoration

Background

This article makes the case that non-native, or "alien,"  species may be useful in some restoration efforts, and should not be overlooked or completely condemned because they are non-native. Such species can provide ecological and socioeconomic services and in some cases speed up successional processes.

Nurse Plant Theory and its Application in Ecological Restoration in Lower Subtropics of China

background

This study examines the mechanisms of the nurse tree effect and ecological factors that influence tree nursing and its relationship to ecological restoration.

Research Goals & Methods

The authors list different pairs of nurse and target tree species, including the broad description of such pairs and research findings of case studies in several locations in lower subtropical China. They also examine the positive and negative feedback loops between nurse trees and target species and explain why the nursing effect occurs.

Restoration of the Cerros Orientales de Bogota - Jardin Botanico de Bogota

The Jose Celestino Mutis Botanic Garden of Bogota works with the Municipal government of Bogota in order to restore and rehabilitate various areas of forest habitat around the city of Bogota.

The most extensive plantings are conducted in the Cerros Orientales, hills located on the outskirts of Bogota. This very steep mountain area had been cleared and was subject to severe erosion, and was planted with exotic pine and eucalyptus throughout the 19th and 20th century. Parts of this forest continue to be grazed for cattle, and many areas have also been invaded by the invasive European gorse (Ulex europaeus).
