The prime objective of quarry management is to ensure a smooth and efficient production process throughout the site. Deadwood, rubble or woody encroachment are potentially impeding this process and thus are seen as disruptive factors. Thus, maintenance cuts of trees and shrubs are carried out, and scree slopes are removed. This causes extra work and disposal costs. But in fact, nature could benefit from a more intelligent disposal process. The aim of our project is to change the current routine for waste materials into a use-orientated concept, which at the same time generates new value for nature. Our target species are smooth snake, grass snake, common lizard and slow worm, because quarries are important secondary habitat for reptiles. All species have already been sighted in the quarry and in the closer vicinity. Through improving their habitats in the quarry, also the regional individual exchange is promoted. Our aim is to optimize habitats instead of creating new installations. This ’use-oriented’ concept is integrated in the ongoing quarry operation and can be adapted to any quarry worldwide. Our main methods are: 1. Relocation of the compost heap based on a new "rotational compost concept" to avoid disturbances in the hibernating period and oviposition phase, and ensuring more diverse temperatures. 2. Optimization of dead wood inventory. 3. Removal of vegetation on the scree slopes to improve places for sun-basking of reptiles.

A good time management is the key - and not only reptiles will benefit!

For the implementation of the proposed measures a good time management is of central importance. Thus, the loss of wintering reptiles or their clutches can be prevented. To measure the project success, a reptile mapping should take place in 2017. But not only reptiles profit from our project: bugs, birds and little mammals could use the created habitats as well. Thus, research in plenty other species is possible.

Low effort and costs for every quarry worldwide!

The project costs are very low. The initial setup of the compost and dead wood places required about 56 working hours only and the total costs were about 2380€. Most of the work is managed with internal personal and machines. Only the shredding is done externally, but this was also the case in the years before. From now on, the annual costs will be approximately 100€, and every third year additional 1300€. Organic waste like dead wood, rubble or woody encroachment as well as stones are present...

Organic waste – How a 'disruptive factor' can increase biodiversity

We evolved an innovative concept of dealing with organic waste in quarries. Instead of seeing it as a disruptive factor it should be seen as a opportunity to enhance biodiversity. Our aim is to optimize habitats instead of creating new installations. This ’use-oriented’ concept is integrated in the ongoing quarry operation and can be adapted to any quarry worldwide. Our main methods are: 1. Rotational compost concept 2. Optimization of dead-wood heaps 3. Optimization of scree slope

Dead wood - not dead at all

Dead wood is an excellent structure for sun-basking with moderate heat-storing capabilities. Reptiles use bark, root plates, dead-wood piles or tree stumps, which can also be used as a hiding place. Dead wood is created frequently in a quarry (e.g. because of maintenance cuts) and it is mostly seen as a disruptive factor, which causes extra work and disposal cost. But indeed it can easily improve biodiversity in quarries if it is cleverly arranged!

New places for sun-basking

Rocky slopes represent important places for basking of reptiles. Therefore, steep, sunny, south-exposed areas should be promoted. Keeping those areas open is of central importance. Even the ‘Artenbiotopschutzprogramm Schwandorf’ recommends the clearing of encroached, shaded rocky slopes and screes.

International jury member Prof. Dr. Rademacher visited Burglengenfeld

Prof. Dr. Rademacher from the international jury visited Burglengenfeld to inspect our project. We explained him and the quarry management as well as other interested managing staff our idea and showed him our implemented measures for the reptiles (compost and dead wood heaps).

Creating excellent oviposition conditions with an intelligent compost concept

All target reptiles need frost-free, protected places for hibernation. Furthermore the grass snake needs a stable temperature of 20–30 °C for successful oviposition. Slowworm and grass snakes use compost heaps as alternative hibernation places as they provide warm conditions and protection against predators. Forest lizards often join. For all these reasons, we worked out a compost concept for the quarry Burglengenfeld, which is implemented from now on in the operation procedure.

Quarries as alternative habitat for reptiles - our target species

Reptiles are increasingly suffering from habitat loss, intensification of agriculture and disturbance caused by human activities, and the remaining habitats are often fragmented. Quarries may constitute alternative habitats due to their high diversity of suitable structures and small-scale heterogeneity. Especially reptiles benefit from this habitat mosaic of wet and dry site conditions, different slopes, exposition and substrates within quarries.

Eine Oase für Reptilien

Am 13. April haben wir im Steinbruch Burglengenfeld eine Reptilien-Oase geschaffen. Dafür haben wir nur Materialien verwendet, die schon im Steinbruch vorhanden waren. Mit wenig Aufwand haben wir die Sonnen-, Versteck- und Eiablageplätze der Reptilien optimiert.
