Blanketing of horses is a very common management routine. Sometimes, this practice may seem unjustified. Therefore, we wanted to investigate the preferences of the horses themselves. First we developed a method by which the horse learned to communicate its wishes. Thirteen horses were trained to associate three different neutral visual symbols presented to them on a board with the actions 1) blanket is taken off, 2) blanket is put on, and 3) stay as is, and subsequently to communicate their wish by pointing at the relevant symbol. These horses had experience of wearing a blanket, but daily routines varied. All individuals which started the training programme succeeded in learning the task. Second, we tested the horse’ opinion under differing weather conditions. Horses normally wearing a blanket were tested with the blanket on, and those which normally did not, without. At the test days, the horse was taken out of its group and placed in a round pen. To be allowed to leave the round pen and join its pals again, the horse first had to make a choice among two symbols presented to them; to stay as is or to have the blanket removed/put on. The test was repeated under different climatic conditions (from -15 to + 20°C, sunny days and days with precipitation and wind) for each horse during winter, spring and autumn 2013. Preliminary results show that all horses made “sensible” choices. Nine out of the 13 horses wanted to remove the blanket for at least one test day. Naturally, cold blooded horses more often preferred to stay without, and shaved warm blooded horses more often preferred to stay blanketed. However, there were individual differences in both groups, showing that owner perception and the horse own opinion not always matched.

Fylkesmannen i Aust-Agder ved miljøvernavdelingen ønsket sommeren 2011 å igangsette en feltbasert undersøkelse med formål å evaluere re-vegetering av engvegetasjon etter gjennomført rydding av gjengrodde arealer på øyene Jerkholmen og Tromlingene i Raet landskapsvernområde (Raet LVO). Videre ønsket Fylkesmannen en vurdering av nødvendig innsats og metoder (herunder beiteregime) for å holde rydda arealer åpne for framtida. Bioforsk i samarbeid med Norsk institutt for naturforskning (NINA) påtok seg dette oppdraget sommeren 2011. Denne rapporten presenterer resultatene fra den treårige overvåkningen (2011 t.o.m. 2013).

Øya Jomfruland ligger ytterst i skjærgården i Kragerø kommune. På øyas vestside, inn mot Jomfrulandsrenna ligger langstrakte sandstrender og strandenger. Rett nord og sør for Tårnbrygga er det kartlagt og avgrenset to verdifulle naturtyper med havstrandenger. Her finnes trua og sjeldne arter i et gammelt, kulturbetinga strandengmiljø. Dette var områder som tidligere ble holdt oppe med bl.a. beiting. Disse strandengene er i dag er preget av forfall og delvis gjengroing. Bioforsk fikk i oppdrag fra Fylkesmannen i Telemark å utarbeide skjøtselsplaner for områdene i tett dialog og samarbeid med grunneierne i området, samt med aktuelle husdyreiere. Denne skjøtselsplanen er for sand- og grusstrandområdet på Haganestranda sør for Tårnbrygga. Skjøtselsplanen danner grunnlag for videre ivaretakelse av biomangfoldverdiene i området med aktive skjøtsels og restaureringstiltak.
