Project description

SUPPORT AREA II „Updating and preparation of new action planes and planes for care of particularly protected plant and animal species “

 1. Project focus

 The project is focused on natterjack toad (Epidalea calamita) and falls within area 1 – preparation of a new action plan. The planned activities are aimed at obtaining all data and information needed for preparation of a salvage programme (SP). One set of activities will consist in the search of literature and data sources. An essential role will be played by the field survey of known localities with both historical and recent occurrence and newly formed localities. The goal of the field survey will be to verify the incidence, to estimate the numbers of animals in the populations and to obtain data on locality characteristics. This will be followed by analysis of biotope locality characteristics. The text of the salvage programme will also contain particular management measures at the individual localities. Another imporant part will be activities associated with the project publicity.

The natterjack toad, beside the scientific (“latin”) denomination Epidalea calamita, can also be legitimately designed by the synonym Bufo calamita. The professional community vary in the opinion concerning the scientific genus name (Frost et al. 2006, Dubois et Bour 2010). However, the use of the genus name is not relevant to the main task of preserving natterjack toad as an integral part of the Czech Republic fauna. In our application, we consistently use the denomination Epidalea in accordance with the Guidelines for Applicants.

 2. Methodology of proposed measures

 Literature and data source search

One of the first activities will consist in the search of the literature and other information sources. Data will be used for drafting the text of the salvage programme (SP), for preparing presentations, a poster, information leaflets, and other outputs.

 

Information leaflets

To inform about the project, two leaflets will be issued, in 5 000 copies overall. The first leaflet, beside information on the project and natterjack toad and the link to the website containing more detailed data, will also call for providing information on the recent occurrence of the natterjack toad, or even on its earlier incidence. The second leaflet will also bring data on the recent occurrence obtained during the field survey as part of the project.

 Seminars

The initial seminar (conference) both for project investigators and public is included in the activities planned for February – March  2015. The closing seminar should be held in February – March 2016. We also envisage active participation in zoology and herpetology conferences and seminars in the Czech Republic.

 Field survey

We plan to verify the occurrence at the most possible number of localities. Preferred are localitites with recorded historical and recent incidence (according to the Location Database of Wildlife Preservation – LDWP, 228 recorded localities until 2014, and database BioLib). Each locality will be visited during the period April-July 2015 as many times would enable us to cofirm/reject the occurrence of natterjack toad and record the required locality characteristics. We plan one to three visits of the locality, each lasting three hours on average (differeing distance from and surface of the locality). In case of clear destruction of the locality (building, backfilling, desiccation, etc.), the time will be used for investigation of the surroundings and search for suitable stations.

We further plan to visit some newly formed localities (sandpits, etc.) in the area of natterjack toad occurrence situated close to the current stations with its known occurrence.

 Methodology of recording locality characteristics

Each visited locality will be documented photographically and its characteristics that could limit the occurrence and reproduction of natterjack toad will be recorded. We will then be able to determine the surface of the locality and of larger pools using GIS. Data obtained from the locality records and subsequently from the maps using GIS will serve to assess the locality characteristics at the level of the water pool itself, associated terrestrial environment, and mutually related water surfaces and terrestrial environment (Doležalová et al. 2012).

The locality recording will contain description of the locality, GPS, number of water pools, surface area of smaller pools, depth of the pools, pool overgrowth, areas without vegetation on the bankcs, soil type, etc.

A note will contain information on negative activities (locality backfilling, recultivation, etc.) and risk factors (e.g. presence of fish, desiccation, distance from used roads).

Using a transportable device, each locality containing water pools (water bodies with stagnant water – inundated sandpits, puddles, basins, etc.) will have measured the basic water characteristics (pH, conductivity, salinity, dissolved oxygen content) that influence amphibian reproduction (Gislén et Kauri 1959, Ferreira et Jesus 1973 ex Wells 2007, Solský 2013).

 Records on individual occurrence

Each visit on a locality with recorded natterjack toad occurrence will record the number of individuals, stage, sex, and potential estimate of the order of numbers (tens, hundreds, or thousands in case of tadpoles). The estimation may also be done in case of high occurrence of vocalizing males. The estimate of the numbers in the population and determination of reproduction in the locality are important factors defining further potential management intervention.

A note will contain informatin on the health status of the toads, apparent damage or hornified skin, potentially caused by chytridiomycosis.

 Processing of locality recordings

All locality recordings will be processed and the information will serve as a basis for drafting the text of SP. The identified biotope characteristics will be processed and prepared for statistical analyses. The recordings on the toad occurrence will be entered to the LDWP database.

 Statistical analysis

The recorded biotope characteristics (including watee properties) will be statistically processed using generalized linear models (GLM) (Doležalová et al. 2012, Solský 2013) and then evaluated. The aim is to find out what characteristics of the environment have a general effect on the presence or number of natterjack toad. A demonstrable effect of a particular factor (both positive and negative) will help in the subsequent protective measures adopted. In each locality we will thus take as a basis the general results obtained by statistical analyses and we will also take into account the specific features of each locality.

Using GIS we can also obtain other characteristics of the localities (e.g., temperature, precipitation, soil) and use them for modeling of the species occurrence (SDM – species distribution modelling) (Kozak et al. 2008, Rödder 2009, Brejcha 2013, Civiš 2013). Linking the characteristics obtained directly in the locality with the presence or absence of toads using BIOCLIM tools (Busby 1991) or MaxEnt (Phillips et al. 2006), we will obtain the map of potential occurrence of natterjack toad and in the following years, this will enable better monitoring of its incidence in these areas.

SP text processing

All data and information obtained will be implemented in the SP text, which will be drafted according to the Synopsis for SP Processing contained in the Concept of salvage programmes and  programmes for care of particularly protected animal and plant species in the Czech Republic, Ministry of the Environment CR, NCA CR, 2014. The text will contain, as an integral part, a proposal of particular management measures at individual localities.

Žabí běh – jarní – 23. běh

Závod na předem odhadnutý čas. Stejně jako si žáby musí umět dobře odhadnout čas, kdy se vydají z místa zimoviště do tůněk a rybníků, měl by si i člověk umět odhadnout čas na překonání určité vzdálenosti v přírodě. Účast v žabích převlecích nebo se žabími doplňky bude vyhodnocena!

Start v 11 hodin

Startovné 50 Kč na delší trase, 30 Kč na trase kratší.

Pro rekreační i trénované sportovce, rodiny s dětmi.
