1.5 参考关于SLM方法（使用WOCAT记录的SLM方法）的调查问卷

2.1 技术简介

技术定义:

To rehabilitate/stabilise distorted wetlands as close as possible to its original state/function.

2.2 技术的详细说明

说明:

Two wetland rehabilitation sites that are part of a large wetland area (15 and 10ha).

Purpose of the Technology: The purpose of the rehabilitation work was to stabilise, landscape and re-vegetate distorted areas to again fulfil their original function in the catchment.

Establishment / maintenance activities and inputs: Maintenance included follow-up on re-seeding distorted areas and alien plant control (cut down plants and treads strips with roundup). Structure maintenance (such as gabions, roads) is also done.
Fire management to protect and manage the area of rehabilitation until such time as it has proved to be stabilised. Leave for ± 3 years before considering burning.

3.1 该技术的主要目的

• 保护生态系统

3.2 应用该技术的当前土地利用类型

注释:

Major land use problems (compiler’s opinion): Afforestation: Pine plantations destroys diversity, also has a major effect on quality & quantity of water run-off, mining opencast activities

Major land use problems (land users’ perception): Production of wood/timber, job creation

Ranching: Game occur natural in this area/nature reserve

Grazingland comments: Area in which these two wetlands are situated is proclaimed conservation land. The aim is to manage the area in an as natural as possible condition as it was historically.

Type of grazing system comments: Area in which these two wetlands are situated is proclaimed conservation land. The aim is to manage the area in an as natural as possible condition as it was historically.

Constraints of nature reserve: Fire management/adjacent to pine plantations

Longest growing period in days: 240; Longest growing period from month to month: Oct - May
