Pirkanmaan uhanalaiset lajit ja luontotyypit -hankkeessa on koottu mahdollisimman kattava tietopohja uhanalaisista lajeista ja luontotyypeistä maakunnan luonnon kestävämmän hyödyntämisen sekä luontoviisaiden ratkaisujen edistämiseksi. Hankkeessa selvitettiin Pirkanmaalla esiintyvien uhanalaisten lajien ja luontotyyppien esiintymien nykytilaa ja niihin kohdistuvia uhkia sekä annettiin toimenpide-ehdotuksia uhanalaisten lajien ja luontotyyppien tilan parantamiseksi. Koottujen aineistojen perusteella Pirkanmaalla esiintyy 16 äärimmäisen uhanalaista (CR), 115 erittäin uhanalaista (EN), yli 190 vaarantunutta (VU) ja noin 370 silmälläpidettävää (NT) lajia. Kymmenkunnalla lajilla on nykyisin Suomessa tunnettuja esiintymiä ainoastaan tai lähes ainoastaan Pirkanmaalla. Hankkeessa määriteltiin maakunnallisten vastuulajien kriteerit ja valittiin Pirkanmaalle vastuulajit, joiden säilymisen kannalta pirkanmaalaiset esiintymät ovat erityisen merkittäviä. Vastuulajeja nimettiin yhteensä 113 ja erityisesti näiden lajien esiintymien nykytilaa ja niihin kohdistuvia uhkia kuvataan raportissa. Hankkeessa selvitettiin myös Pirkanmaalla esiintyviä uhanalaisia luontotyyppejä ja koottiin eri organisaatioissa hajallaan olleet luontotyyppiaineistot yhtenäisiksi paikkatietoaineistoiksi. Tarkastelujen perusteella Pirkanmaalla esiintyy yli 180 luontotyyppiä, joista noin 110 (60 %) on arvioitu uhanalaisiksi Etelä-Suomessa. Uhanalaisten luontotyyppien osuus Pirkanmaalla vastaa uhanalaisten luontotyyppien osuutta koko Etelä-Suomessa (59 %). Valtaosalla Pirkanmaan luontotyypeistä esiintymien nykytila on tarkastelujen perusteella varsin samankaltainen kuin luontotyyppien uhanalaisuusarvioinnin perusteella Etelä-Suomessa keskimäärin. Merkittävimmin Pirkanmaan vastuulajeihin ja uhanalaisiin luontotyyppeihin vaikuttavat tulevaisuudessa metsätalouteen liittyvät toimet. Vastuulajien kannalta tärkeitä uhkatekijöitä ovat myös avoimien alueiden umpeenkasvu etenkin perinnebiotoopeilla ja niiden lajeilla, mutta myös rannoilla ja harjumetsissä. Uhanalaisilla luontotyypeillä merkittäviä uhkia ovat edellisten ohella rakentaminen ja soiden ojitus. Vaikka uudisojituksia ei nykyisin enää tehdä, ovat kunnostusojitukset sekä vanhojen ojitusten kuivattava vaikutus edelleen merkittäviä. Uhkatekijöitä sekä vastuulajien että uhanalaisten luontotyyppien kannalta ovat myös vesien rehevöityminen ja likaantuminen, vesirakentaminen sekä vesien säännöstely. Hankkeessa tuotettiin Pirkanmaan luonnon monimuotoisuuden parantamiseksi ekologisen tiedon pohjalta laadittuja toimenpide-ehdotuksia, jotka käsittelevät eri luontotyyppien ja lajien uhkien vähentämisen keinoja ja hoidon ja ennallistamisen kohdentamista sekä luontotiedon parantamista. Hanke on toteutettu yhteistyössä Pirkanmaan elinkeino-, liikenne- ja ympäristökeskuksen, Pirkanmaan liiton ja Suomen ympäristökeskuksen (SYKE) kesken. Kootut aineistot, tehdyt tarkastelut sekä ehdotukset tarvittavista jatkotoimenpiteistä ovat tärkeää taustatietoa, kun Pirkanmaalle laaditaan vuonna 2021 alueellinen biodiversiteettiohjelma Suomen ensimmäisenä maakuntana. Tuloksia tullaan hyödyntämään myös tulevassa maakuntakaavaprosessissa.
