SUMMARY:ALT x Pittsburgh Zoo: Girty's Woods Restoration Workday Series 1
DESCRIPTION:Week 1: Trail Building\n\nRegistration is required so we can communicate in case of any necessary changes. \nEvery Friday throughout the month of May\, ALT is teaming up with the Pittsburgh Zoo to restore wild space in Girty’s Woods. Over the course of five weeks\, we’ll work together to build a trail\, remove invasive plant species\, plant native trees\, and install trail markers and signage. Together we’ll restore a scenic hiking route to a green space that supports native wildlife and promotes the health and wellbeing of its neighbors. \nWeek 1: Volunteers will use rakes\, hoes\, and mattocks to widen\, level\, and define the tread of a trail which was roughly built in the spring of 2025. \nVolunteers should expect to hike about two miles on varied terrain. Long pants and closed-toe shoes are required. Long sleeves and a brimmed hat are recommended. Tools and gloves will be provided\, but volunteers are welcome to bring their own gear if they prefer. \nWorkdays are rain or shine but will be rescheduled in the event of thunderstorms or high winds. \n\nTICKETS

SUMMARY:Invasive Plant Management- Churchill Valley Greenway
DESCRIPTION:Protect the greenway from invasive vine species\n\nRegistration is required so we can communicate in case of any necessary changes. \nChurchill Valley Greenway\, the former site of a golf course and country club\, is steadily re-wilding with the care of stewards and volunteers. A common sight on disturbed lands are invasive plants\, which can outcompete the native flora and be a detriment to native wildlife. Join us to tackle one invasive plant species in particular: Mile-a-Minute vine (Persicaria perfoliata). \nVolunteers will use gloves and garbage bags to uproot vines and remove them from the greenway. Preventing the spread of this fast-growing invasive plant species will aid in our restoration efforts in the forests and meadows of Churchill Valley Greenway\, and we can’t do it without you! \nVolunteers can expect to walk up to two miles mostly on paved walking paths and are asked to work at their own pace and comfort level. Tools and gloves will be provided. Light snacks and water will be provided; please bring your own reuseable water bottle. Closed toe shoes and long pants are required. Due to the prickly nature of mile-a-minute vine\, long sleeves are recommended. There are no restrooms on site. \n\nTICKETS

SUMMARY:Volunteer Workday- Girty's Woods Trail Maintenance
DESCRIPTION:Registration is required to participate in this volunteer event. \nVolunteers are invited to join in a steward-led trail workday at Girty’s Woods!

We can’t do it without you! \nParticipants should expect to hike at least a mile on uneven terrain. Close-toed shoes and long pants are required. Tools and gloves will be provided. \nTrail maintenance activities will be determined on an as-needed basis weeks before the event date. Tasks will likely include: cutting vines and pruning branches impeding the trail\, removing growth and debris from the trail tread\, pulling invasive plant species\, picking up litter\, and defining the trail tread with rakes and hoes. \nFollowing registration\, you’ll receive an email with more details. Another pre-event email will be sent out one to two days prior to the workday to ensure you have all the facts you need to ensure a successful trail day! \nTICKETS
