Partioleirin vaikutuksia ympäristöön : Case: Roihu

Työn tarkoituksena oli selvittää, miten partiolaisten suurleiri Roihu, joka pidettiin Hämeenlinnan Evon Pitkäniemenkankaalla, vaikutti ympäröivän alueen kulumiseen ja pohtia, miten mahdollisia kulumisvaurioita voisi seuraavilla leireillä välttää. Työtä varten valittiin GPS-paikantimen avulla joitakin mittauspisteitä, joiden ympäristöä dokumentoitiin kuvaamalla. Roihu-leirillä ympäristöä kuormittivat eniten maastopysäköinti, harmaavesi, purku- ja rakennusleiri sekä tallaaminen. Leirillä kevyestikin suojatut alueet säästyivät yllättävän pienillä vaurioilla. Ongelmana oli myös tiedon saanti. Leiriä rakentamassa oli pari tuhatta vapaaehtoista, joilla oli kullakin oma vastuualueensa. He olivat kiireisiä ennen leiriä ja leirin jälkeen pian tavoittamattomissa ympäri maata. Avainlukujen dokumentointi leirin aikana auttaisi sekä partiolaisia että muita toimijoita.The purpose of this thesis was to study the erosional impact on the environment caused by the Roihu Finnjamboree Scout Camp, which was the largest scout camp ever organized in Finland. The thesis also deals with what the benefits would be if the areas were protected and fenced in advance. In this case the study was done by visiting the area in advance and during the Roihu Finnjamboree, as well as after the jamboree. For research, different types of control points were selected by GPS, and the environment around the points was photographed. During the study it became clear that parking cars and using machines while building and dismantling the camp were the most harmful for the environment. An unsolved problem was also the grey water from the camp. Trampling in the program area and eating areas had a big erosional impact on the terrain. It also became clear that even very light fencing, stairs and duckboards would protect the terrain quite well. It was hard to get information for the study. The builders of the camp were volunteers. Before the camp they were in a hurry and after the camp all were split around the country. Also, the volunteers knew their own tasks well but not necessarily the general view. Documentation of the key figures during the camp would help scouts and the other operators
