Answer added in Biodiversity & Conservation10 Do you know how many species of critically endangered terrestrial mammals you have in your country?By Totem SaaJosef Weissbacher · University of BristolAccording to the Red Book of Austria [SPITZENBERGER (2005) Red List of the Austrian Mammals (Mammalia) in ZULKA (ed., 2005) The Red Book of Endangered... [more]According to the Red Book of Austria [SPITZENBERGER (2005) Red List of the Austrian Mammals (Mammalia) in ZULKA (ed., 2005) The Red Book of Endangered Animals of Austria, Federal Environment Agency, Vienna] 4 mammals must be considerd extinct (southern birch mouse Sicista subtilis, wolf Canis lupus, wildcat Felis silvestris and Schreibers bat Miniopterus schreibersii, which occur exeedingly rare as single vagrants), The equal number of mammals in Austria is critically endangered (Bavarian pine vole Microtus bavaricus, black rat Rattus rattus, greater horseshoe bat Rhinolophus ferrumequinum an lesser mouse-eared bat Myotis oxygnathus. Recent monitorings show wolf coming back to Austria from Bavaria and Czechia, and wildcat rediscovering eastern Austria from Slovakia. The current status of these two species therefore may be better than in 2005.Following

[more]Your "satellite sampling approach" seems to be similar to point-distance (k-nearest) methods, which are common in forest inventory for counting of tree numbers, stand volume, etc. I use them e.g. for counting of damaged trees by ungulate peeling, which often has a similar clustered distribution in a given area (e.g. a wood owners lot). The german book "Leitfaden zur Waldmesslehre" by KRAMER/AGCA 1995 gives some statistical background to those sampling methods. As far as i know there is a lot of english literature to distance methods, too.Following

Article: Neue Aspekte bei der Anwendung des Vergleichswertverfahrens bei der Flächenbewertung in der Land- und Forstwirtschaft
H. Haimböck, A. Fichtinger, J Weissbacher und F. Wolfslehner[show abstract] [hide abstract]
ABSTRACT: Due to an imperfect and inefficient market situation of agricultural property markets in Austria the authors present an new approach for the valuation of agricultural land based on the different purpose of the utilisation of the valued sites (Original Text in German)Der Sachverständige. 01/2005; 29:105-108. -

Article: The use of organic and mineral fertilizers in reforestation and in revitalization of declining protective forests in the alps
[show abstract] [hide abstract]
ABSTRACT: BIOSOL1 and BACTOSOL2 organic fertilizers based on residue from commercial antibiotic production, were tested as an alternative to mineral fertilizers in reforestation and in revitalization of Norway spruce stands (Picea abies) affected by forest decline. Due to its slow release of N and its stimulation of root growth, the organic fertilizer was superior to mineral fertilizer in enhancing growth of spruce planted in nutrient poor soil with low nutrient retention capacity, especially when combined with magnesium carbonate fertilizer. In mature stands, basal area increment responded positively and significantly to both mineral fertilizer and BIOSOL. So far no pronounced effects of fertilizer treatment on seed production and viability were observed. Fertilization in the moderate amounts employed had no adverse effects on microbial activity in the soil and mycorrhizal status and thus seems to be a safe method to increase tree vigor without dramatically changing site parameters.Water Air and Soil Pollution 01/1990; 54(1):567-576. · 1.63 Impact Factor
