The best native trees for ecologically valuable gardens

Trees are true treasures for local biodiversity. They provide food for animals (leaves, blossoms, fruit, and wood) and offer structures for nesting and breeding sites. Planting an ecologically valuable tree can therefore greatly enhance the entire local ecosystem.
And now to the best native trees for ecologically valuable gardens.

Further options for ecologically valuable gardens

Here are some examples of how you can further enhance the ecological value of your garden:

• Leave the leaves in autumn or rake them into a pile. This provides nutrients and shelter for many animal species.
• Leave some of the fruit hanging for the animals. 
• From an ecological perspective, it is often better to leave an old tree standing than to plant a new one.
• Cultivate as many different plants as possible. Two different plants are better than two identical ones.
• Plant in particular umbellifers. Umbellifers have many small flowers that are an easily accessible food source for wild bees, butterflies, and beetles. Examples from this plant family include: dill, cow parsley, fennel, caraway, angelica, chervil, and wild carrot.

Create habitats for insects, birds and other animals:    

• Create a compost heap: A compost heap is an attractive ecosystem for worms, ants, insect larvae, and fungi. When you later spread the mature compost in the garden to fertilize other plants, it enriches the soil life throughout the entire garden. 
• Create a pile of branches or small logs. A woodpile provides shelter, food, and nesting material for numerous animals. Toads, hedgehogs, lizards, wild bees, beetles, and spiders, in particular, feel at home here. If you create such a pile in your garden, make sure it can last for many years.
• Create a wild corner, for example a hedgerow. It offers nesting sites, shelter and hiding places for many bird species; food for wild bees and butterfly caterpillars; as well as berries and nuts for birds and mammals. If you use the edges of your property for this, you might not even need any more space.
• If you have a lawn: Is there perhaps a corner that you don't mow and can leave the grass and flowers standing? 
  
• Build or buy nesting boxes for birds or bats. If you want to attract a specific bird species to your garden, you can look into which nesting boxes are particularly suitable for that species.
• Avoid using pesticides and mineral fertilizers. While such aids may seem to have a positive effect in the short term, in the long run you'll have better soil and a more stable ecosystem without them.

Additional materials for a more valuable ecosystem 

You can also enhance an ecosystem by adding additional materials. Here are some examples:

• Stones. Stones can provide valuable habitats for lizards, ground beetles, and spiders. Examples include unplastered dry stone walls or herb spirals. Or simply a few larger stones used as decoration.
• Sand: Approximately 75% of all wild bee species nest in sandy soil. You could, for example, build a small sandarium. Choose a sunny and rain-protected location, dig a 30-centimeter-deep hollow, and fill it with loamy sand and lean soil.
• Water: Especially on hot days, put out a water dish. This allows a variety of animals to drink from it. It's important to change the water regularly, as otherwise pathogens can multiply. Stagnant water can also become a breeding ground for mosquitoes. If you have enough space, a small pond could enhance the local ecosystem.

An ecologically valuable garden takes time.

Add something new: a new tree, a compost heap, a wild corner. And then give nature time. If you create good structures and give your garden time, a valuable ecosystem will develop almost by itself. Avoid chemical fertilizers or pesticides as much as possible.

Care of ecologically valuable trees

Once your tree is established, it will still need some care, especially during the first 3-5 years. For example, it's important to water it well during this time. Giessen. 
Depending on the soil and tree species, it can also be helpful to düngen.
And depending on the tree species, there may also be a Video editing worthwhile. One important point to note: 
Avoid pruning your tree or hedge during the breeding season. According to the Federal Nature Conservation Act, only the current year's shoots may be removed from hedges between March 1st and the end of September, but even then, the hedge must be thoroughly checked for nesting birds beforehand.
