18 <br />3.b.Hazelnut ParkRecommendations <br />Contracted and Initial Management <br />Hazelnut Park has ongoing contracted work which will reduce the mature buckthorn population in the <br />northern woodland as outlined in Table 3.b.1. This work will continue through spring of 2027, employing a <br />combination of critical period cutting during the growing season, and foliar herbicide application in autumn <br />to control resprout and seedling buckthorn. Volunteer and city coordinated efforts have already significantly <br />reduced or eliminated the buckthorn and invasive shrub population in the southern woodland, with native <br />species planted at the edge of the woodland along the paved path. As this work continues, GRG will <br />coordinate seeding the woodland to initiate an accelerated and directed succession process towards a <br />composition like the mesic woodland systems listed in Table 3.a.1. This work will still be within the Outdoor <br />Heritage Fund project to facilitate sustainable habitat that can be stewarded into the future. <br />Continued Maintenance <br />Once contract work in the northern woodland concludes in 2027, work in late 2027 and 2028 should focus <br />on planting native trees and shrubs, and seeding native graminoids and wildflowers, with species selected <br />from one of the appropriate plant community types listed in Table 3.a.1. The goals beingto provide direct <br />competition for space to the buckthorn or other woody invasive species populations attempting to <br />proliferate, and indirect competition by offering alternative food sources for birds, which are the main vector <br />for buckthorn proliferation. Planting should occur in spring or autumn to ensure the best conditions for <br />planting survival. Seeding for additional understory diversity is also advised and should happen sometime <br />during autumn through spring for best germination and establishment rates.As the native plants establish in <br />2028 and onward, targeted foliar herbicide applications should focus on controlling invasive herbaceous <br />species as, and if, they invade into the open spaces left by buckthorn removal. Similarly, from 2028 onward, <br />the woodland should periodically receive renewed buckthorn control using critical period cutting and foliar <br />herbicide application, or alternatives described later, every 2 to 3 years. <br />The southern woodland in Hazelnut Park will need continued follow up/ maintenance work focusing on <br />controlling buckthorn and establishing a mesic hardwood forest community. Although the southern <br />woodland did not receive contract work under state grant funding, volunteer efforts have successfully <br />eliminated most, though not all, buckthorn stems. Thus, follow up work will follow a similar trajectory to the <br />north woodland with growing season cutting and autumnal foliar herbicide application for at least the next 3 <br />years followingfullremoval of large buckthorn stems. Following that, the southern woodland can follow the <br />same trajectory as the northern woodland with seeding, planting, herbaceous invasive control as needed, <br />and continued buckthorn suppression, as described in the previous paragraph. <br />Alternative control methods to herbicide application and critical period cutting include prescribed fire and <br />goat browsing. Depending on when the native plant understory establishes throughout the northern and <br />southern woodland areas, independently, prescribed fire can be used to further inhibit understory <br />invasion/re-invasion by invasive woody and herbaceous species. Woodland burns should be conducted in <br />autumn, when leaf litter is thickest and herbaceous vegetation continuous enough to carry fire. Meanwhile, <br />goat browsing can be used as an alternative to fire and herbicide to suppress all woody species within an <br />enclosed area. Goat browsing would be best used in areas where invasive shrubs and trees have <br />overwhelmed the understory again,and they can be employed year-round.
