Delaware has marked the 75th anniversary of its state parks by planting its 75,000th tree, completing a five-year target to expand greenery across its 17 parks.
asserted
Delaware → mark → parks
According to an October 20 announcement by the Delaware Department of Natural Resources and Environmental Control (DNREC), the milestone was reached on October 19 at Trap Pond State Park, where officials planted a Liberty Tree near the Bob Trail by the causeway.
uncertain
officials → accord → causeway
The planting also coincides with the 250th anniversary of the signing of the US Declaration of Independence in 2026.
asserted
planting → coincide → 2026
The achievement fulfils a commitment made by DNREC’s Division of Parks and Recreation in its 2021–2026 strategic plan to add 75,000 trees to Delaware State Parks by the end of 2026.
asserted
achievement → fulfil → 2026
The programme forms part of a wider state initiative, A Tree for Every Delawarean (TEDI), which aims to plant at least one million trees across Delaware by 2030, equivalent to one for every resident.
asserted
which → form → resident
More than half a million trees have already been added statewide through TEDI, according to the state.
uncertain
trees → add → state
The 75,000-tree milestone is specific to the state park system, while the million-tree target covers the broader statewide initiative.
asserted
target → cover → initiative
TEDI is a partnership involving DNREC’s Division of Climate, Coastal and Energy, the Delaware Forest Service’s Urban and Community Forestry programme and other stakeholders.
asserted
TEDI → involve → Climate
The initiative is part of Delaware’s wider plan to respond to climate change, and it encourages residents, businesses and communities to take part in planting trees.
asserted
it → respond → trees
American holly takes centre stage
asserted
holly → take → stage
The final tree in the state parks’ 75,000-tree effort was planted as a Liberty Tree, a reference to trees that served as symbols of freedom and gathering places in the American colonies before the Revolutionary War.
asserted
that → plant → War
The American holly, Delaware’s state tree, was given a place of honour in 16 of the state’s 17 parks as part of the anniversary initiative.
asserted
holly → give → initiative
The final planting at Trap Pond brought the parks’ tree-planting commitment to its target.
asserted
planting → bring → target
DNREC Secretary Greg Patterson said Liberty Trees historically acted as natural landmarks and meeting places, as well as symbols of freedom.
asserted
Trees → say → freedom
The new plantings, he said, represent the state’s commitment to protecting its natural resources and creating places where people can gather and enjoy the outdoors.
asserted
people → say → outdoors
The anniversary effort included a mix of native tree species, not just American holly.
asserted
effort → include → species
Cherry, oak, persimmon, maple, sycamore and pine were among the varieties planted throughout the park system.
asserted
Cherry → plant → system
Tree shelters were also used to protect young trees from extreme weather and wildlife, helping them establish themselves after planting.
asserted
them → use → planting
Which parks received the most trees?
asserted
parks → receive → trees
The planting effort was spread across the park system, with some locations receiving substantially more trees than others.
asserted
locations → spread → others
Killens Pond State Park recorded the highest number, with 29,900 trees, followed by Trap Pond State Park with 29,200.
asserted
Park → record → 29,200
White Clay Creek State Park received 10,072 trees, while Auburn Valley State Park received 5,110 and Bellevue State Park received 447, according to DNREC.
uncertain
Park → receive → DNREC
The figures for these five parks total 74,729 trees, meaning the remaining trees were planted across other locations in the system.
asserted
trees → total → system
Rather than focusing only on the number of trees, the programme also considered where planting could deliver environmental benefits.
uncertain
planting → focus → benefits
According to DNREC, trees were selected and positioned to enhance existing forests, improve wildlife habitats, create riparian buffers along waterways, control erosion and stabilise areas beside rivers and streams.
uncertain
trees → accord → rivers
Planting was also intended to encourage natural forest succession, diversify vegetation beneath the forest canopy, replace dead trees and expand native plantings.
asserted
Planting → intend → plantings
These objectives are significant because trees can help protect soil, improve water quality and provide food and shelter for wildlife.
asserted
trees → help → wildlife
The state’s TEDI programme also identifies trees as important to climate action, alongside their role in improving air quality and supporting ecosystems.
asserted
programme → identify → ecosystems
Volunteers helped complete the five-year target
asserted
Volunteers → complete → target
The milestone was achieved with funding from several sources, including TEDI, Environment Stewardship funds, Friends groups and other public and private contributors.
asserted
milestone → achieve → TEDI
Volunteers from local park support groups, schools, colleges, corporate partners and the wider community also helped with planting.
asserted
Volunteers → help → planting
Delaware Governor Matt Meyer credited the combined efforts of state agencies, volunteers and community organisations for the achievement.
asserted
Meyer → credit → achievement
He said the trees would benefit families using the parks in the future and described the milestone as a way of strengthening the parks for the next generation.
asserted
trees → say → generation
Matt Ritter, director of DNREC’s Division of Parks and Recreation, also acknowledged the contribution of volunteers, corporate groups and individuals, alongside park staff, in completing the target within the planned timeframe.
asserted
Ritter → acknowledge → timeframe
Although the 75,000-tree goal has been reached, planting work is continuing.
asserted
work → reach → ?
DNREC said another 88 trees were scheduled to be planted at Fox Point State Park on October 28, as part of ongoing efforts to improve park habitats.
asserted
trees → say → habitats
The additional planting comes after the formal milestone rather than being necessary to meet the original target.
asserted
planting → come → target
From three parks to a statewide conservation effort
Delaware’s state park system began in 1951 with three parks.
asserted
system → begin → parks
It has since expanded to include 17 state parks and 22 nature preserves, alongside the Brandywine Zoo and Indian River Marina.
asserted

The system covers more than 27,000 acres, according to the state’s anniversary announcement.
