As a local resource and environmental education provider, CoraHartshorn Arboretum (CHA) believes in leading the way to a more sustainable future. We strive to influence students, program attendees, and everyday visitors to shape and modify behaviors and attitudes that promote environmental stewardship and conservation.
The purpose of this document is to guide CHA’s practices on every level to include environmentally aware choices and decision making.
CHA will conserve natural resources by:
- Reducing waste through the Triple R Philosophy (reduce, reuse, recycle)
- Limiting water and energy consumption
- Encouraging alternative transportation
CHA will minimize negative impacts on the environment by:
- Investing in and buying environmentally conscious products and paper goods
- Following EPA regulations for cleaning supplies whenever possible
- Continuing to use compost and limiting our waste stream
Live Animals and Wildlife
As an educational center with live animals CHA provides the upmost care for live specimens and follows NJ DEP and Federal regulations.
- All displays involving live animals will serve as an educational purpose.
- We do not accept specimen donations from private citizens (unless education staff has made special consideration and deem that the donation will serve as an educational opportunity).
- CHA staff will provide proper care and nutrition for the animals; follow standards for maintaining live specimens and consult experts as necessary.
- CHA makes it a priority to accept only native species from now forward.
- As an arboretum we are aware of the effects of white-tailed deer on our tree and plant populations. By maintaining about 15 plus acres of a deer fence we control and monitor both wildlife and plant life on township property.
- Through our conservation efforts, we have created a sanctuary for residential and migratory bird species. You can download a checklist of the birds you may find on the CHA’s grounds by clicking here: CHA Bird Checklist
CHA land and gardens are to reflect the natural habitat of the area.
- CHA will use and promote water-efficient landscaping.
- We routinely remove invasive and exotic plants species such as Norway Maple, Garlic Mustard, and Wine Berry and replace them with native plants.
- Herbicides/pesticides/fungicides are only used on grounds under specific management protocols. For example, we need to treat our Ash Trees with direct trunk insecticide injections to combat the Emerald Ash Borer. We treat our Hemlocks via a systemic bark spray and our one Crabapple Tree with a foliage hand spray fungicide. Without these treatments the trees would die.
- Outdoor compost bins are maintained and used as fertilizer.
- Staff and volunteers will provide upkeep and maintenance on trails. Pruning and harvesting of plants or trees is done only when posed as a threat to visitors and alike.
Cleaning Products and Office Supplies
Many cleaning products and paper supplies have a direct impact on our environment. CHA strives to use alternative cleaning products that are less harmful to both people and the Earth.
Health to humans and the environment is taken seriously by the Arboretum. By using only natural, bio-based cleaners we keep our staff and visitors safe from toxic chemicals.
When possible we follow the Green Seal certification when purchasing cleaning products, which state that products:
- Cannot irritate skin, be corrosive to the eyes or cause illness or injury when inhaled, swallowed or absorbed
- Cannot contain 2-butoxyethanol, alkylphenol ethoxylates, phalalates, heavy metals, optical brighteners or ozone-depleting compounds
- Cannot contain ingredients determined to be mutagenic by the UN
- Cannot contain ingredients considered reproductive toxins by the State of California Safe Drinking Water and Toxic Enforcement Act of 1986
- Cannot contain any chemical considered carcinogenic by the International Agency for Research on Cancer, the National Toxicology Program and the EPA
- Must be biodegradable
- Performs at least as well as a conventional product
Pest control at CHA should be undertaken through an Integrated Pest Management (IPM) program where a variety of techniques are used to try and control pests. CHA promotes prevention before all other methods.
- As an arboretum we must take procedures to insure our trees are healthy. The Emerald Ash Borer is highly destructive to our native Ash trees, therefore CHA must treat these trees once a year with an insecticide labeled for the targeted pest, and used according to label specifications.
- Besides our treatment for Ash, Crabapple, and Hemlock trees CHA is an herbicide and insecticide free site.
Triple R Philosophy (Reduce, Reuse, Recycle)
Through our programs, events and everyday practices CHA promotes the three R’s: Reduce, Reuse, and Recycle.
- First and foremost we reduce our impact by limiting the amount of products bought and used at the Arboretum.
- Whenever possible we reuse non-biodegradable materials such as plastic and glass that offer multiple functions from containers to educational resources.
- Water catchment – CHA has a rain barrel near the cold frames in back of the addition. We use some of the water for plants in the cold frame. We also have a rain garden in the front of the Arboretum that uses runoff from the Arboretum’s roof.
Our non-renewable resources are valuable and limited. We strive to conserve and invest in alternatives when it comes to energy consumption.
- Automatic lights are installed in many of our rooms and offices to insure electricity is used only when necessary.
- CHA has regular energy inspections and audits and takes into consideration energy-efficient recommendations.
- Thermostats are programmed to use heaters and air conditioners sparingly.
- When looking for new appliances CHA will choose the most efficient and feasible technology. We recognize the label Energy Star as a leader in environmental design.
Cora Hartshorn Arboretum recognized that climate change is one of the most pressing environmental issues today. Personal and community-based approached to carbon footprint control is important and necessary for the future health of our world.
- The Arboretum is conveniently located a couple blocks away from the Short Hills Train Station. We encourage our visitors to use this way of travel and other alternatives when traveling to and from all CHA events and programs.
- We encourage carpooling whenever possible. Parking is limited and you’ll save on gas!
- While we have no fixed amount of shrubs, trees, or plants that we try to plant each year, our land management plan developed in partnership with the Township of Millburn necessitates the planting of native plants species each year. The type and number of plantings varies from year to year depending if an area has been cleared of invasive species or if the tree canopy has opened because of blow downs from storms.
- For each of the past three years, we have probably planted 1000 plants, including shrubs, saplings, ferns and grasses; some of these were raised from seed, some purchased, and some transplanted. We believe the new planting ultimately will have a positive effect on CHA’s carbon footprint as we try to recreate habitat for native insects and birds.
Outside User Groups
CHA encourages the groups that use our facilities to follow our lead in conservation methods and standards.
- When planning your birthday party consider biodegradable plates and cutlery instead of wasteful alternatives.
- If using the A/C ensure that doors and windows remain closed.
- Recycle all left over materials (consider recycled wrapping paper for gifts and re-usable food containers instead of plastic).
Compost when possible. We have worm bins and outdoor composts for use.
- When finished using spaces turn off all lights, ceiling fans and appliances.
- We prohibit balloons not because we don’t like fun but because balloons persist in the environment and can be extremely harmful to wildlife.
