Restoration Ecology Group

On Wednesday, May 17 we transported sheep to the island in the Cep II sand pit. The sheep will again graze experimental plots for restoration of dry grasslands where bird's-foot trefoil (Lotus corniculatus) started to overgrow the psamophytic vegetation. This management is again carried out by our colleague Alča Bartošová and her fluffy "management tools". Their 6-day "holiday" ends on Monday and we greatly thank all the protagonists, this year for the third time. 

On Monday April 24, a one-day excursion to the Kosov quarry near Jihlava took place. This excursion was a part of Ecological restoration course taught by Klára Řehounková. Students had an opportunity to go through the quarry an explore it in detail - from the oldest parts with grown trees and nice forest species in the herb layer, to disturbed open plateaus, floors and shallow water pools.

Industrially mined peat bog Branná was next stop on the route. For comparison, they visited also preserved, although formerly extensively mined, peat bog Červené blato. Students could see extensive stands of endangered marsh rosemary (Rhododendron palustre) in the oldest parts of the peat bog.

Karel Prach is in the USA again, this time not for a half of a year, but only for a month. Karel was invited by a leading expert Prof. Lawrence Walker from the University of Nevada. Together, they write a book entitled "Comparative Plant Succession between Terrestrial Biomes of the World". The book will be finished during the first half of the next year and is going to be published in the Cambridge University Press.

This document, International Standards for the Practice of Ecological Restoration – including Principles and Key Concepts, provides standards to guide practitioners, operational personnel, planners, managers, regulators and funding agencies involved in restoring degraded ecosystems anywhere in the world – whether terrestrial, freshwater, coastal or marine. It places ecological restoration into a global context, including its role in conserving biodiversity and improving human wellbeing. Karel Prach is co-editor and you can download this document here.

Our former student Lída Vlková succeeded in the 6th edition of a competition of projects for environmental protection "Jihočeská ratolest" with her master thesis. She won in the category of bachelor's and master's theses. In her study, Lída focuses on restoration of extracted peatland Soumarský most in the Šumava National Park which has been seriously damaged by peat extraction. She studied establishment of two species typical for peat bogs - bog cranberry (Vaccinium oxycoccos) and bog-rosemary (Andromeda polifolia). Congratulations Lída!

In the same competition but in different category, NGO Calla and our group as its partner succeeded with the project on low-cost maintaining open sandy habitats. This novel project does not hesitate to engage public in the nature conservation. It utilizes geocaching not only to show beautiful and interesting places to people but also to protect valuable sites.

Mud on our boots has not dried yet - so hot this news is. We have established three flowering strips in the city park Stomovka in collaboration with the Municipality of České Budějovice. We prepared seed mixtures of native grassland species appropriate to moisture and soil conditions in the park. The seed mixtures were supplied by the German company Rieger-Hofmann GmbH (which cultivates regional seed mixtures according to the system of individual regions in Germany, outreaching to the Czech Republic). Since the amount of seeds per square meter was very small, it was necessary to add a crushed corn which helps to sow the plots evenly but does not affect germination of the seeds. We are looking forward the result of our effort! In the next season, the flowering aspect will not probably be fully developed. However, in the summer of 2018, we will hopefully enjoy flowering blossoms and fliting insects.

Our working group participated in the Conference on Ecological Restoration with several talks and posters. Karel Prach started with a keynote speech and summarized the findings about spontaneous succession. This was followed by talks focused on successional stages emerging in post-mining sites and their importance for nature conservation (Klára Řehounková, Lenka Šebelíková). The possibility of using recreational activities as a low-cost tool for nature conservation in model localities in south Bohemia was presented in a special session chared by Klára Řehounková and Robert Tropek. The research of our group was also represented with two posters - Anna Müllerová addressed vegetation succession in wetland areas in sand pits and Kamila Lencová focused on determining of the potential for colonization of the central European flora in human disturbed sites.

The project „Rekreační aktivity jako nízkonákladový nástroj ochrany přírody v postindustriální krajině: modelové lokality v Jihočeském kraji“ was financially supported by the South Bohemian region.

Part of our group went for a week-long excursion focused on vegetation classification which took place under the leadership of Karel Prach. The introductory photo depicts our professor having a late breakfast in a French style. The vegetation in the foreground was not classified even after professional disputation with local botanist Tomáš Tichý (Administration of PLA Český Kras).

We visited spoil heaps after uranium mining in Příbram, new PLA Brdy and oak woods with Quercus pubescens in Český Kras.

Classification of vegetation on former spoil heap, currently a dump Buštěhrad at the end of the day - Atriplecetum nitentis!
