Other Site Characteristics

Rytilammen ympäristö on hyvin rehevää ja monimuotoista suoaluetta. Lammen ympäristössä on mm. luhtalettoa (LuL), koivulettoa (KoL) ja lettorämettä (LR). Suon reunoilla on ruohokorpia. Puusto suon reunoilla on säilynyt melko luonnontilaisena. Arkkukari on rinteen alla oleva pieni lähteinen ja lettoinen suo. Keskeisin alue on lierosammalrimpilettoa (ScoRiL) ja lettorämettä (LR). Suon reunoilla on lähdekorpea.

4.2 Quality and importance

Rytilammen alue on merkittävä lettoisten soiden ja uhanalaisten putkilokasvien esiintymispaikka. Se on lajistollisesti yksi arvokkaimmista alueista Siika-, Pyhä- ja Kalajokilaaksojen alueella. Arkkukari on pienuudestaan huolimatta arvokas lähteinen ja lettoinen suo, jolla on monipuolinen sammallajisto. Peruste D kohdassa 3.3: vaaleasara, pussikämmekkä, rimpivihvilä, litteävita ja nevaimarre ovat alueellisesti uhanalaisia lajeja. kilpukka on vaatelias vesikasvi ja lettotähtimö ja hentosuolake ovat rehevien kasvupaikkojen, mm. lettoisten soiden lajeja. Hoikkavilla on etelässä harvinaistunut märkien kasvupaikkojen laji. Suojelutavoitteen määrittely: Kaikki tietolomakkeen taulukoissa 3.1 ja 3.2 mainitut luontotyypit ja lajit (lukuun ottamatta edustavuudeltaan luokkaan D luokiteltuja luontotyyppejä ja populaation merkittävyyden osalta luokkaan D luokiteltuja lajeja) kuuluvat alueen suojeluperusteisiin ja kaikkien niiden suojelutavoitteena on vähintäänkin alueen merkityksen säilyttäminen osana verkostoa. Lisäksi alueen suojelussa ja hoidossa painotetaan seuraavia tavoitteita: Alueella vallitseva luontotyyppien ja lajien sekä niiden elinympäristöjen tila säilytetään turvaamalla luonnon omien prosessien mukainen kehitys. Alueella vallitseva luontotyyppien ja lajien sekä niiden elinympäristöjen tila säilytetään hoitotoimenpiteillä.
