Analysis of the Inventory findings resulted in a number of <br /> recommendations with regards to preservation of Greenwavs and Open Space <br /> Corridors; potential areas for additional rare plant surveys; and sites to consider <br /> for proactive mana�ement and protection. A Greenway is defined as "privately <br /> or publicly owned corridors of�en space which often follow natural land or <br /> water fea�ures and which are primarily mana eg d to protect and enhance natural <br /> resources". Greenwavs ma i�ncorporate recreational trails, active recreational <br /> spaces such as athletic fields and golf courses, and other public open spaces that <br /> mav provide rudimentar e�colo_gical functions and values. <br /> Map 3A-5 is a Conceptual Greenway Corridor Ali�nment developed bv HCDES <br /> takin� into account a number of ug iding elements, includingti <br /> - Hi�h and Moderate quality natural areas <br /> - Other unique and/or ecolo i�call�significant areas <br /> - Riparian areas including bodies of water and wetland complexes <br /> -Natural corridors with natural/semi-natural areas (streams. draina�ewavs, <br /> floodplains, steep slopes) <br /> -Connectivity to surrounding communities identified natural corridors <br /> - Lar�e publicl�nd privately owned protected open spaces <br /> - Semi-natural areas that occur immediatelv adjacent to natural areas <br /> - Areas that would serve as lo�ical links between natural areas, particularly those <br /> that have potential for restoration to natural ve�etation. <br /> Recommendations from HCDES with regards to greenways and open space <br /> corridors include connecting lar�e publicly owned open spaces with natural or <br /> semi-natural vegetation within �reenwav corridors: providing connectivity <br /> City of Orono Community Management Plan 2008-2030 Page 3A-11 <br />
