Many animals find suitable living conditions in little field woods. Some species go hunting for so called "agricultural pests" from there. They penetrate into the arable land upto 500 metres deep. Field woods lodge a flora and animals, that differ from the field land. That is necessary for the open countyside in its function as wind-brake, moisture-storage and filter for the "seeds of pests".

Field woods grow along the arable land upto 10 metres high brake the wind still 300 metres behind by 2 or 3 forces. It reduces the soil erosion to 50%. The air humidity is higher in its wind shadow than on the free, unprotected arable land. The cultivated plants growing in this area are less exposed to aridness than in the middle of the field and have better conditions of growth. The different biotope-structure hinders the spread of animals and plants, which are damaging to the agriculture.

The Great grey shrike is a song-bird despite of its hooked beak. It's the greatest representative of the rare native shrikes. It inhabites half-open countysides with field woods and lines of bushes, where it builds its nest 2 to 20 metres high. For seaching food it needs primitive structures of vegetation and raised hide standpoints, from where it carries off insects, little mammals and lizards and birds from time to time. Before the consumption of hymenopters like bumble-bees, wasps and hornets it takes the sting off. So they are made harmless. This behaviour is inherent in the shrikes.

The Fox is an adaptable and many-sided hunter, that takes everything he can overcome. But its main preys are voles. It also likes to have berries. Foxes spend one part of the year as loners. The male stays close to the female after the mating season in January and February. The vixen gives birth to 3-12 youngs in her den. She scarcely leaves her den in the first three weeks, the male brings the food during this time. After the fourth week both parents bring the food. The youngs are completely independent nearly after 4 months. Then they are bitten away from the vixen and have to look for their own territory.

The Roe deer is our smallest native species of deer. Only the male (roebuck) has 25 cm long antlers, which are shed in October or in the early November every year.

The really adaptable animals live seperately, in twos or in familiar associations according to the season and the living space. The 1-2 youngs (fawn) are born in May-June. They live seperated from each other, hidden away in the vegetation, well camouflaged by their spotted coat. The Roe deer looks after her youngs for suckling only 40 minutes daily. The Roe deer leads their fawns after 3-4 weeks.

Roe deers need food rich in protein, first of all buds and young sprouts.

The high density of Roedeer could be dangerous for the regeneration of the wood, while damages in the fieldland (because of the surplus of food rich in proteins) scarcely won't incur.
