-====== Enchanting Fallow ======
+====== Magic of the Fallow ======
+//Insects need food and nesting places in sufficient variety, quality and connectivity. During
+the complex life cycle, different habitats are required for reproduction, larval stages, food
+intake and hibernation.//
+The more structural diversity there is in a landscape, the more likely insects are to find
+suitable living conditions and habitats there.
+===== Habitats for butterflies =====
+Many insect species have been deprived of their livelihood in recent decades - through
+increased management intensity of grassland, the loss of fallow land, the elimination of
+small structures in the agricultural landscape (such as raines, hedges, flower and herb-rich
+hems and wetlands), growing homogeneity of cultivated areas, and loss of land through non-
+agricultural use.
+Butterfly species are very good bioindicators. If the most sensitive and vulnerable species of
+a claim type are protected by improving their habitats, other habitat-typical species are also
+promoted.
+Terrestrial microhabitats are habitats in the smallest space, which are characterized by their
+own microclimate (temperature, light, humidity), which is determined by the type and
+composition of the soil (e.g. also the proportion of raw soil), the type, density, and height of
+the plants growing there, and the prevailing light conditions (shading).
+Many species of butterflies often prefer a warm-dry microclimate and lay their eggs on
+young host plants such as umbellifers, e.g. dill, parsnip, wild carrot over raw soil or gravel,
+which warms up in the sun and creates a warm-dry microclimate preferred by many
+butterfly larvae.
+Some butterflies also suck on wet soil or puddles to absorb dissolved minerals. Leaving
+unsealed surfaces offers possibilities.

+Microhabitats can be examined more closely with drones. The information obtained can
+then be used in ecological field research for larger areas, so that predictions can be made,
+for example, about the suitability of butterfly egg deposition in a landscape. The method of
+bridging scales (fine to large) can also be used to assess and verify the effectiveness of
+nature conservation measures. Thus, statements about the ecosystem functionality of a
+landscape can also be made.
+===== Fallow land development =====
+The structure of the vegetation is particularly important for the occurrence of insect species.
+A coexistence of all successional stages is necessary.
+From the initial stage of a vegetation-free, bare raw soil, a stable final stage of a
+bioeconomic (plants, animals, fungal society - climax society) develops independently
+without regulatory intervention through various intermediate stages, which is adapted to
+the site-specific environmental factors (climate, soil). Provided that the environmental
+factors allow it and no further disturbances occur, fallow, abandoned successional areas in
+these latitudes develop in succession (primary and secondary succession) via newly
+colonizing pioneers, such as prokaryotes, mosses, lichens, into stands of grasses, herbs,
+perennials, shrubs, and bushes and even forests. Weakly competitive species will be replaced
+by stronger species over time.
+This development is often disturbed or altered by e.g. storms, fire, rockfall, cattle kicking,
+machinery, ploughing or clearing. In this way new, &quot;disturbed&quot; areas are created.
+Disturbed structures in ecosystems are often positive and absolutely necessary for the
+preservation of many, and here in particular the highly endangered butterfly species.
+It would be necessary to reestablish extensive forms of use, small-scale mosaics with
+different uses and also dates of use and unregulated components of use. This would create
+important disturbance sites (in forests and on marginal yield sites or also on municipal green
+spaces or in private gardens).

+===== What the individual can do: =====
+Allow structural diversity, changing fallow land, in your environment as well - on a small and
+large scale. Give ruderal surfaces, mostly fallow raw soil areas, a chance or create fallow
+islands yourself. Allow leaves, rootstocks, puddles, and dead plant parts to lie wild. Cairns,
+wood piles, open ground, cracks, or holes in the ground offer important microstructures for
+many insects.
+Then enable magical, fluttering diversity of insects and thus make a valuable contribution to
+the preservation of species diversity (biodiversity).
