2.1 Short description of the Technology

Definition of the Technology:

The technology is supposed to increase afforestation with native species within the area by supporting natural seed dispersal

2.2 Detailed description of the Technology

Description:

Planting areas are pre-selected based on local condition and optimal rate of potential seed dispersal (prevailing dry-wind direction, distance to remnant seed banks etc.). The areas are partially vegetated or have previously been treated with fertilizer (and seed) to facilitate surface stabilization, improved soil qualities and vegetation succession. Only native species are planted in these seed bank "islands"; mainly birch and a mixture of willow species. The islands/patches are scattered over the restoration area in order to get as much effectiveness out of the technology in the long run.

Purpose of the Technology: The purpose with the technology is to halt further land degradation and facilitate natural succession within the area undergoing restoration. In the long-term, it should substantially reduce wind and water erosion. It should also lead to increased biodiversity, enhanced water availability and accelerated carbon sequestration (in soil and vegetation). The overall restoration task is to increase the resilience of the ecosystems against natural hazards; such as volcanic activities.

Establishment / maintenance activities and inputs: For the first years, the plants in the seed banks islands are yearly treated with a small amount of fertilizer. The nutrient level within the areas is still very low and hardly enough to support sufficient annual plant growth.

Natural / human environment: In the long-term, the technology is expected to substantially increase biomass production, re-build soil qualities, accelerate carbon sequestration and secure water availability within the rangeland and the adjacent ecosystems. Increased tree and diverse vegetation cover will reduce and even halt the sand drift that still creates challenges for inhabitants in adjacent villages, on farmsteads and within the summerhouse clusters, scattered around the area. As the degraded rangeland is in the vicinity of an active volcano (Mt Hekla) the technology is also expected to increase ecosystem resilience against natural hazards like ash and pumice drift and reduce potential offsite damages caused by these materials.

3.2 Current land use type(s) where the Technology is applied

Comments:

Major land use problems (compiler’s opinion): Vast parts of the area are heavily degraded due to unsustainable land use through the centuries in combination to harsh climate and frequent volcanic eruptions. The major land use problem are related to the fact that the concerned ecosystems collapsed long time ago and despite all restoration efforts implemented within the area for over 100 years, the systems are still highly dysfunctional. Their carrying capacity is limited and even light livestock grazing can keep further vegetation succession down. Passive restoration might take place where the livestock grazing has been excluded but in most cases some technologies are needed to "kickstart" the ecosystem and break their negative resilience against changes.

Major land use problems (land users’ perception): They are fully aware that the ecosystems are in a poor condition and restoration is needed in order to push improvements forward. They acknowledge that grazing of collapsed ecosystems can maintain the dysfunctional of the systems and hinder ecological improvements. Nevertheless, in many cases they believe the harsh climate and volcanic activities are the main contributors to land degradation - that livestock grazing and the grazing carrying capacity of the rangeland are not fundamental issues in this context.
