Limestone Quarry Restoration - Evaluation plan of restoration methods for Alvar establishment on northern Gotland

Abstract (Swedish)
Alvars are globally rare habitats with rich and distinctive vegetation-communities. Alvars are found on limestone bedrock which is also subject to quarrying for cement production. The increasing global need for cement results in either expanding existing quarries or the opening of new ones. Current legislation requires the restoration of limestone quarries after they are closed for quarrying and there are visions of using alvar as the target habitat of such restoration.
The purpose of this thesis is to provide a plan of evaluation for a restoration project carried out by Cementa AB on northern Gotland. The test sites of the project are situated in the Western quarry of Slite cement production plant.

The purpose of this thesis is to provide a plan of evaluation for a restoration project carried out by Cementa AB on northern Gotland. The test sites of the project are situated in the Western quarry of Slite cement production plant.
The evaluation plan was formed by reviewing existing literature in the field of limestone quarry restoration and analysis of alvar characteristics. Biotic and abiotic variables were included in the evaluation plan based on studies of the composition of plant species on alvar and patterns in the levels of soil nutrients when comparing to other habitats. Sampling frequency was based on the method of existing national monitoring programmes in combination with the time-plan for the Western quarry.
All studies about limestone quarry restoration were from North America, but since alvar communities across continents share similar conditions, and sometimes even support the same plant species and community types, they are suitable for an initial comparison. However, additional studies conducted outside America, preferably as close to Sweden as possible, would strengthen the results (Less)
