CONSERVATION PRACTICES AT RAVEN’S NEST

PLANTING NATIVE TREES
Since our arrival Raven’s Nest Nature Sanctuary in March 2008, Vincent designed a multi-faceted Ecological Restoration Strategy to create healthy, diverse and resilient Wildlife Habitats for generations to come. Since the creation of our Nature Sanctuary, we remain commited to offset our carbon footprint. Trees are a wonderful force in Nature because they absorb carbon dioxide from the air through a process called photosynthesis. In exchange trees give off oxygen as a waste product. Scientifically speaking, the direct action of Planting Trees at our Nature Sanctuary has provided us with the rewarding opportunity to help offset your carbon footprint over the lifetime of that tree.

When planting and nurturing native trees, we use both our efficient 20,000 gallon Rainwater harvesting System, and the rain water that we have collected via our Passive Rainwater Techniques throught the 42-acre Nature Preserve. The awesome results since 2008 are due to the precious rainwater collected during the Monsoon and Winter seasons, as well as the Organic Compost that we produce daily from our organic food scraps, and the valuable Mulch from dried Mesquite leaves and non-native grasses. We also strive to maximize the benefits of the trees we plant to the surrounding wildlife habitat by strategically locating them during planting.

Planting trees to reduce carbon dioxide is more important than ever given the effects global warming is having on our planet! At Raven’s Nest Nature Sanctuary we are very mindful of the daily actions that contribute to an excess of greenhouse gases, mainly Carbon dioxide (CO2) in the atmosphere and their detrimental environmental consequences. Every time we turn on the lights, drive a car, or take a flight we are unwittingly producing CO2, which countless scientific studies have repeatedly demonstrated that increase greenhouse gases – which are directly linked to the rise of global temperatures and major climate changes. The greenhouse gases responsible for global warming are measured in units of carbon dioxide or CO2. Hence, the amount of CO2 that each person is responsible for producing is termed a Carbon Footprint.

At Raven’s Nest Nature Sanctuary we are constantly implementing a holistic approach aimed at reducing our Carbon Footprint. We modify our behaviors – making green changes both big and small – to help reduce the amount of carbon that we place into the atmosphere. We try to minimize the remainder of the CO2 that we produce through a “sustainable carbon offsetting lifestyle” – planting trees, rainwater harvesting, organic gardening & composting, etc. Firmly believing that every inch of land is sacred, we have actively restricted the amount of land devoted to buildings and human artifices of any kind, including parking and driving areas. We have rehabilitated many of the former dirt roads into thriving wildlife habitat.etc . . . Our aspiration on a daily basis is to be carbon neutral.

Hence, by Planting Trees at Raven’s Nest Nature Sanctuarywe strive to:
- Help offset the Carbon Footprint – 1 mature tree can absorb one ton of carbon dioxide over the lifetime of that tree!
- Help the Environment
- Contribute to the unique Sky Islands Biodiversity
- Benefit Wildlife and improve Native Habitats

ETHNOBOTANY LANDSCAPE BY DISCOVERY CENTER

As a professional Ethnobotanist, Vincent wanted to create an Edible, Medicinal, and Useful Landscape surrounding the Sky Islands Discovery Center. Therefore, every native species he planted has important human uses. Some species provide food, others herbal medicine, while select plants produce parts useful for rope, tools, soap, aromatherapy, and other uses. Additionally, all of the species listed below support native pollinators – either as a larval food source and/or as a source of nectar. Thus, countless species of insects, butterflies in particular, as well as dashing Hummingbirds of various species are a common sight at Raven’s Nest, especially where we have performed Ecological Restoration.

The species Vincent planted around the Sky Islands Discovery Center include:
Trees
- Scrub Oak – edible acorns, tannic acid for medicine
- Velvet Mesquite – edible pods, edible sap, firewood
- Catclaw Acacia – firewood, topical wound care from leaves
- Arizona Rosewood – wood-working
- Velvet Ash – medicine
- Netleaf Hackberry – edible fruit
- Desert Willow – edible flowers, medicinal leaves
- Texas Mulberry – edible fruit, rope from inner bark
- Western Soapberry – soap and medicine from fruit
- Alligator Juniper – edible fruit, medicine from leaves, aromatherapy from sap and leaves
- Arizona Cypress – medicine and aromatheraphy from leaves, tinder from inner bark, glue from sap








Shrubs
- Cat Claw Mimosa – medicine from leaves
- Apache Plum – tinder from shedding bark
- Evergreen Sumac – edible/medicinal fruit
- Wild Cotton – rope from inner bark
- Fremont Wolfberry – edible fruit
- Mariola – aromatherapy and medicine from leaves
- Dalea – aromatherapy and medicine from leaves and flowers
- Graythorn – edible fruit
- False Indigo – kindling from stems and dye source
- Mexican Elderberry – edible flowers and fruits, fire-by-friction sets from wood
- Wright’s Silktassel – medicinal leaves – used as an anti-malarial medicine in WWII
- Oreganillo – spice and aromatherapy from leaves
- Desert Honeysuckle – basketry
- Seepwillow – hand-drills for fire-by-friction kits, medicine from leaves
- Arroyo Willow – basketry from stems, medicine from leaves and inner bark
- Broom Snakeweed – tinder, medicine from leaves








Succulents
- Cane Cholla – edible fruit, woody skeleton for tool handles
- Chainfruit Cholla – edible fruit
- Santa Rita Prickly Pear – edible fruit, medicinal pads
- Mountain Yucca – edible fruit, rope from leaves, medicine from roots
- Soaptree Yucca – edible flowering stems, soap and medicine from roots, fire-by-friction sets from dried flowering stalk
Other Plants
- Arizona Cottontop grass – tinder, basketry




In addition to supporting a myriad of native pollintaors, the wide range around the Sky Islands Discovery Center also furnish critical habitat for a broad spectrum of other wildlife. Bobcats, Mountain Lions, Coyotes, Common Gray Foxes, Ringtails, Northern Raccoons, 4 species of Skunk, Collard Peccari, White-Tailed Deer, as well as a plethora of birds, reptiles and amphibians.

ETHNOBOTANY LANDSCAPE BY SOUTHWESTERN HOUSE

The hard clay soil proved no easy nut to crack, but soon Vincent’s efforts were paying off. As a professional Ethnobotanist, Vincent wanted to create an Edible, Medicinal, and Useful Landscape surrounding the house. Therefore, every native species he planted has important human uses. Some species provide food, others herbal medicine, while select plants produce parts useful for rope, tools, soap, aromatherapy, and other uses. Additionally, all of the species listed below support native pollinators – either as a larval food source, as a source of nectar, or in some other capacity. Thus, countless species of insects, butterflies in particular, as well as dashing Hummingbirds of various species are a common sight around the house – all in response to Vincent’s ecological restoration efforts. Vincent lovingly planted each species with xeriscaping principles in mind. He created swales for each species, heavily applied mulch in the ground and atop it, and created countless windbreaks with both rocks and logs. His final touch was a custom-made soaker hose system that delivers water efficiently, greatly helping to conserve it. The transformation of the landscape and al of its biota are in spectacular evidence everywhere throughout the preserve.
