Jeudi 6 juin toute la journ\u00e9e, une op\u00e9ration de piochage du v\u00e9r\u00e2tre va \u00eatre r\u00e9alis\u00e9e au Col de Porte pour lutter contre la prolif\u00e9ration d\u2019une plante toxique dans les prairies p\u00e2tur\u00e9es et tester l\u2019effet de l\u2019action m\u00e9canique.<\/span><\/div>\n
Cette op\u00e9ration, men\u00e9e depuis 6 ans par le Parc naturel r\u00e9gional de Chartreuse, commence \u00e0 porter ses fruits.<\/span><\/div>\n

\n<\/span><\/div>\n
Le ver\u00e2tre<\/span><\/strong><\/div>\n

\n<\/span><\/div>\n
Cette plante d\u2019alpage, sans int\u00e9r\u00eat pastoral, est toxique pour les hommes comme pour les animaux domestiques. Elle fleurit entre juin et juillet. En automne, la plante perd son caract\u00e8re r\u00e9pulsif pour le b\u00e9tail et peut provoquer des troubles digestifs importants apr\u00e8s consommation. Du fait de sa toxicit\u00e9 cette plante est non d\u00e9sir\u00e9e par les \u00e9leveurs. L\u2019objectif est donc de restaurer une prairie d\u2019alpage et de permettre de conserver une prairie saine pour les vaches.<\/span><\/div>\n

\n<\/span><\/div>\n
Etudier l\u2019incidence du piochage m\u00e9canique<\/span><\/strong><\/div>\n

\n<\/span><\/div>\n
Depuis 6 ans, une exp\u00e9rimentation est en cours sur les prairies du Col de Porte. 3 placettes ont \u00e9t\u00e9 mises en place pour \u00e9valuer l\u2019efficacit\u00e9 du piochage \u00e0 la main.<\/span><\/div>\n
Chaque placette a un secteur pioch\u00e9 et l\u2019autre non et chaque ann\u00e9e l\u2019op\u00e9ration consiste \u00e0 comparer le nombre de pieds pour chaque secteur et la taille de chacun.<\/span><\/div>\n
Ce protocole permettra d\u2019affirmer l\u2019int\u00e9r\u00eat de cette m\u00e9thode afin de sensibiliser les \u00e9leveurs au fait d\u2019utiliser moins d\u2019herbicides. Ce qui est favorable pour la qualit\u00e9 de l\u2019eau, les plantes, les vaches et la sant\u00e9 des \u00e9leveurs.<\/span><\/div>\n
Du temps est n\u00e9cessaire n\u00e9anmoins pour voir un r\u00e9sultat significatif, mais il semblerait qu\u2019il y ait moins de pieds qui repoussent sur les parcelles pioch\u00e9es et de plus qu\u2019ils soient plus fins. Pour confirmer ces pistes d\u2019am\u00e9lioration cette ann\u00e9e des mesures de la largeur des tiges vont \u00eatre faites.<\/span><\/div>\n

\n<\/span><\/div>\n
Une action collective<\/span><\/strong><\/div>\n

\n<\/span><\/div>\n
Cette op\u00e9ration, men\u00e9e par le Parc naturel r\u00e9gional de Chartreuse, permet de cr\u00e9er une journ\u00e9e conviviale entre tous les acteurs du territoire qui participent : les \u00e9leveurs (groupement pastoral du Charmant Som), le gestionnaire (ONF), la F\u00e9d\u00e9ration des alpages de l\u2019Is\u00e8re et le Parc (gestionnaire du site Natura 2000 du Charmant Som).<\/span><\/div>\n
A cette occasion, une sensibilisation particuli\u00e8re \u00e0 la pr\u00e9servation de l\u2019environnement peut \u00eatre men\u00e9e pour d\u00e9montrer que des solutions alternatives aux produits chimiques existent.<\/span><\/div>\n","protected":false},"excerpt":{"rendered":"
