Die Arbeitsgruppe wurde 1987 als privatwirtschaftliches Institut gegründet und firmiert seit Ende 2019 als GmbH. Sie besteht aus Fachleuten aus den Bereichen Biologie, Agrarbiologie, Landschaftsökologie, Forstwissenschaft, Geographie, Umweltsicherung und Landschaftsarchitektur.
Die fachlichen Kompetenzen und langjährigen Erfahrungen unserer MitarbeiterInnen ermöglichen uns die Bearbeitung eines breiten Spektrums komplexer Aufgabenstellungen. Unsere Arbeitsfelder reichen dabei von tierökologischen Fachbeiträgen im Rahmen von Naturschutz- und Eingriffsplanung bis zur Projektleitung in größeren Vorhaben. Zudem sind wir im Bereich der naturschutzorientierten Forschung und der Erarbeitung methodischer Standards für Planungsvorhaben tätig.

On the dimensions of amphibian passages and the creation of compensation habitats - recommendations for improved practice.
Despite a long tradition in the construction of amphibian tunnels, there is insufficient quantitative information available for such structures longer than approximately 20 to 25 meters. Even the sustainable usability of short culverts is doubtful, so far as those with small opening widths are concerned. Additionally, due to inadequate maintenance, the effectiveness of amphibian tunnels, measured against the avoidance requirement, is in some cases severely limited in the medium term. Based on a literature review, consultations, and empirical values, this article provides information and recommendations for dimensions of amphibian tunnels/underpasses in the context of target values for minimum crossing rates for amphibian individuals. The priority for sufficient avoidance and mitigation is always the creation or optimization of functional compensation habitats on both sides of the road in conjunction with barriers and individual, large-volume underpasses (every 500 meters to the main migration direction). For cases in which this is not or not completely possible, recommendations are given for culvert dimensions (height and width) depending on their length. A reform of prior “standards” and practice is
necessary.
This article pinpoints the location of the first German record of the Bull Bush-cricket (Polysarcus denticauda) near Tübingen, summarizes the few other data from this area and discusses the development of the species‘ presence and its habitat situation there. Its occurrence near Tübingen at the end of the 19th century, at around 315-320 m above sea level, was at lower altitude than the closest occurrences on the current northern edge of the species‘ sub-range in Baden-Württemberg, which start at an altitude of > 390 m above sea level. In view of the species‘ biology and habitat requirements, it seems most plausible to conclude that the Bull Bush-cricket disappeared completely or largely from the Tübingen area early, due to fluctuations in abundance and presence-absence at the edge of the range as a result of various weather conditions. Other factors that endanger the species today were probably not yet very pronounced at that time.
Es wird über das dritte Seminar zum Thema „Laufkäfer in der Naturschutz- und Planungspraxis“ (hier Modul I) der Akademie für Natur- und Umweltschutz Baden-Württemberg berichtet, das vom 15.-17. Mai 2023 in Bad Buchau im Naturschutzzentrum des NABU (Naturschutzbund Deutschland e. V.) am Federsee stattfand und u. a. eine Exkursion an die obere Donau beinhaltete. Es steht in der Reihe von Fortbildungsveranstaltungen zum Themenbereich „Artenwissen stärken –
Artenvielfalt erhalten“. Laufkäfer stellen eine wichtige Gruppe für naturschutzfachliche, landschaftsökologische und umweltplanerische Fragestellungen dar. Die Berichte über das erste und zweite Seminar im Jahr 2022 (Modul I und II) am Federsee und in der Nördlichen Oberrhein-Niederung wurden ebenfalls bereits publiziert. Im Rahmen des vorliegenden Berichts werden insbesondere die Aufsammlungsergebnisse der Exkursionen während des gegenständlichen Seminars (hier: 72 Arten) dokumentiert, um diese allgemein verfügbar zu machen. ----------------------------------------Ground beetle seminar at Federsee and Danube. Report from the 3nd course of the Academy for Nature and Environmental Protection Baden-Württemberg on this insect group in May 2023 with a list of recorded species. A report is given of the third seminar on „Ground beetles in nature conservation and planning practice“ (here Module I) of the Academy for Nature and Environmental Protection Baden-Württemberg, which took place from 15-17 May 2023 in Bad Buchau at the nature conservation centre of NABU (Naturschutzbund Deutschland e. V.) at Federsee and included, among other
things, an excursion to the upper Danube. It is part of the series of training events on the topic of ‘Strengthening species knowledge - preserving biodiversity’. Ground beetles, which form an important and species-rich group for nature conservation, landscape ecology and environmental planning issues – and for which a comprehensive basic work is available for Baden-Württemberg – have been included in the course programme for the first time in 2022. Reports on the first and second seminar at Federsee and in the Northern Upper Rhine Lowlands have already
been published. In this report, the results of the field trips during the seminar in question (here: 72 species) are documented in order to make them generally available.
The biologically active part of the earth‘s upper crust is not limited to a layer of the earth‘s surface only a few meters thick but extends much more heterogeneously in its vertical dimension. It extends locally down to a depth of 2 kilometres or more in caves and, in any case, several decametres through gaps, fi ssures, and crevices. With numerous examples from several continents, this article provides an insight into the diversity of subterranean habitats and the species that colonize them. The term „soil“ is interpreted broadly and discussed in the context of the subterranean part of the Earth‘s „critical zone“. Reference is also made to the potential refugial
and corridor function of subterranean habitats in the context of climate change. Soil protection and the protection of subterranean habitats must be considered in a more differentiated and broader way than the „classic“ view, which often focuses on productive, biomass-rich, habitats that are preferred by higher plants. Extreme site conditions often play an important role for biodiversity on the soil, in its uppermost layers and in the „deep soil“; without or with only low suitability for higher plants and without accumulation of biomass, partly also with a dynamic through recurring processes that interrupt soil succession in small (mosaic-like) or large areas. In
any case, in terms of biodiversity, this must be given equal consideration or case-by-case, and area-by-area, even priority over other possible soil functions.
