2.1 技术简介

技术定义:

Cutting of wild ferns for fodder production and to mitigate pasture degradation.

2.2 技术的详细说明

说明:

Ferns are considered pioneer plants because Wherever there is fertile, acidic and well drained land Ferns (Pteridium sp.) preceed shrub species and the encroaching of forest species. Ferns that develop on pastures are fairly un-palatable to grazing livestock and completely disregarded by animals when the plant is fresh. The plant is thus usually mowed down to clear pastures and make way for more palatable species which would otherwise be suffocated by the presence of ferns. However, once cut down, dried and gathered, ferns can be used during the winter months (when the animals are in sheds or stables), both as a source of fibre and as bedding in deep litter housing systems (in place of the more common use of straw).

Purpose of the Technology: Improve pasture quality and gathering of fodder/ litter

Establishment / maintenance activities and inputs: End of summer/beginning of fall farmers use to cut ferns in the fields where they are diffused. Usually they use tractor whit a cutting equipment. As they get dry (it takes from 3 to 6 days according to air temperature and humidity) the ferns are collected and stored for winter use, either as fodder or litter housing.

Natural / human environment: The context of production is characterised by a medium level of mechanisation (only the most demanding operations are carried out using mechanical means), the production system is essentially mixed, a small part is destined for personal consumption whilst the bulk of production is destined for local markets. The property is predominantly privately owned but also includes some public land, especially in the case of pasture land. Most farms in the area are livestock farms whilst the agricultural component is destined exclusively for private consumption. The technique is mainly applied on higher latitude pasture land (because of the presence of acidic soils) which are not particularly stony.

Major land use problems (compiler’s opinion): Pasture degradation (shrub encroachment)
Major land use problems (land users’ perception): Pasture degradation (shrub encroachment)
Semi-nomadism / pastoralism: Shepherds use the area for summer grazing and move downhill in winter
Grazingland comments: the technique is applied in livestock farms which raise both cattle and sheep and goats seeing as
fresh ferns are un-palatable to all grazing species.

4.7 影响成本的最重要因素

描述影响成本的最决定性因素:

The technique does not require specific investment given that the necessary equipment is usually already available on farm in the case of medium to large size livestock farms. The work is carried out in autumn when the machinery are not generally in use as haying operations are usually finished in the summer months.
If the farm does not own suitable machinery it can be rented at a cost of €40 per hour.
