Project Model Benjamin Farm follows a triple bottom line model, where the design and site programming aim to satisfy certain environmental, economic, and social goals. The overlap of these three areas represents a comprehensive planning and design solution with the potential to meet all of the various project goals. In this scheme for Benjamin Farm, it is proposed that commercial animal husbandry, specifically raising goats and sheep, benefits all of the stakeholders involved and helps meet the project goals.

Browsing by goats has been shown to be successful in controlling invasive plant species in the Northeast. It can also be used to slow the growth of young woody vegetation, preserving early successional habitat that is increasingly rare as a result of human development.
Environment
omy Econ
Providing land for raising livestock creates an economic opportunity for a profitable farm startup in the face of ever rising property values. Using livestock for landscape management represents the avoided cost of traditional land management techniques for SLT.
Economy
Providing opportunities for local farmers preserves Scarborough’s heritage as a farming community and provides an opportunity for agricultural education. The use of livestock to manage the landscape will improve birding and other wildlife viewing.

New England Cottontail (Sylvilagus transitionalis) Overview The only native cottontail rabbit in New England, the New England Cottontail (NEC), is the target of conservation actions in Maine that hope to restore habitat for this state-listed species.
Habitat Loss NEC once ranged throughout southern New England and eastern New York. Today, habitat loss due to human development and suppression of natural disturbances has restricted the species to five unconnected subpopulations covering only 14% of their historic range. In Maine, only an estimated 250-400 individuals persist.
Historic Range Extant Populations
Habitat Requirements NEC thrive in thickets - shrubby, early successional habitats - where they can safely browse on herbaceous plant material, as well as the foliage, stems, buds, and bark from woody shrubs. Examples of this habitat type that can easily be managed for on Benjamin Farm are old fields and shrub swamps. Specific habitat requirements include: ≥20-25 Acres Habitat fragmentation is the major threat to the species. Smaller patches have much higher winter mortality rates and cannot support the varied gene pool sustainable NEC populations. NEC is very similar in appearance to the more common Eastern Cottontail, which was introduced in the 1800s
20,000 stems/acre - or 46 stems per 10’ X 10’ area - This density of woody stems includes only plants that are ≥20” tall and ≤3” in diameter (See page C8). Invasive Species Although many native species found on the site Control create the type of habitat that NEC prefer, they tend to do so at the expense of native species that provide a higher quality food source.

Livestock-Driven Solution Overview
Selective, or targeted, grazing by livestock is gaining popularity as a land management strategy. This proposal considers utilizing a combination of sheep and goats to help fulfill its ecological and economic goals.
Environment Improves Habitat Sheep and goat droppings are small and widely scattered, fertilizing the landscape. Browsing by goats improves thicket habitat by increasing stem density and slowing succession. Grazing by sheep increases native plant diversity in grasslands, which is beneficial for pollinators, erosion control, and water filtration. Sustainable Lessens the need for petroleum fuels and chemical herbicide application in land management activities. Invasive Species Goats (and sheep) will feed on a variety of invasive Control species, unlike free roaming browsers (deer) that selectively browse on native plant material. They can eat plants that are toxic to other animals Goats destroy seeds in their digestive tracts, diminishing the invasive seed bank.

Heritage Maintaining a pastoral aesthetic on the property helps to preserve Scarborough’s agricultural heritage in the face of continued suburban development. Education Combining public lands and commercial agricultural presents an opportunity for educational programming
Economy
Cost Effective Avoided labor and equipment costs create savings for the Land Trust. Raising livestock on public lands makes farming startups possible in the face of increasing real estate prices and shrinking profit margins in agriculture. Meat, Dairy, Byproducts from livestock make land management Wool on the site about more than just saving money. Goat meat production is one of the fastest growing segments of American livestock production.
Goats vs. Sheep - Feeding Patterns Goats Sheep Page B6
Sheep are grazers; they eat herbaceous plants near to the ground (as well as foliage and fresh stems on some young woody species). Goats are browsers; they selectively feed on new stems, buds, bark, and foliage on woody plants up to 7-8’.
Lease-Driven Solution Overview
The development of a progressive lease contract is essential to the success of the project. This document defines the responsibilities of the owner and the leaseholder, particularly the division of labor to fulfill the project’s land management goals. Developing a replicable process for costneutral land management and sustainable farming on public lands has wider implications in revolutionizing conservation, invasive species control, and habitat restoration strategies.

Observation Platforms Overview
The observation platforms are inspired by Chilean architect, Rodrigo Sheward Giordano from The School Of Architecture at the University of Talca. His Pinohuacho Observation Deck was designed with the mission of “Bring[ing] architecture where there is none, to reach where the commission is not expecting an answer.” This philosophy, along with the use of natural materials and framed landscapes, is fitting for Benjamin Farm. The structure is humble; it praises the natural materials on the sight and celebrates the landscape it’s a part of.

Experiential Concept 1 - Wetland Focus
This concept shows Benjamin Farm as if it was managed primarily for wetland habitat management. Maximizing wetland in this way would have the greatest effect on pasture placement and the least effect on the existing forest cover (which is mostly upland). Page B8
NEC Habitat Water Quality/Headwater Protection Wildlife Education Less farming infrastructure Boardwalk trails
Experiential Concept 2 - Agriculture Focus
This concept shows Benjamin Farm as if it was managed primarily as pasture for livestock. Maximizing pasture in this way would suggest a focus on grazing livestock (sheep and cows) rather than browsers. This concept also supports clearing upland forest areas for additional pasture space. With expanded grazing potential comes the need for more livestock housing and processing facilities.

Existing Road The proposed cover type distribution at Benjamin Farm was determined through analysis of existing conditions and the location of pasture areas from the site’s past. Based on the importance of New England Cottontail habitat, priority is being given to maximizing scrub-shrub wetland and altering the shape of forest areas to increase shrubby edge habitat. The trail system is designed to let users experience the different cover types on the site. Its configuration was also influenced by the desire to demonstrate changes in light, vegetation, scale, etc. as visitors pass from one plant community to another. This method for trail layout diversifies the outdoor recreation component of the project, while simultaneously increasing opportunities for educational installations and signage. Page B10

Benjamin Farm Proposed Site Plan
DETAIL 1
Main Entrance, CSA, and Event Space
In this proposal for Benjamin Farm, the site represents a merger of agriculture, public recreation, and ecological restoration. While agricultural activity and ecological restoration exist in contradiction to each other under traditional land management strategies, this model creates a mutually beneficial relationship between the two. The use of livestock to manage wildlife habitat makes this possible; creating conditions for a profitable business through invasive species control and preservation of early successional habitat. The development of recreational trails and observation platforms further cements this new relationship between agriculture and ecological restoration. In addition to the physical connection of these once-opposing landscapes via the trail network, the establishment of large event spaces, a CSA, improved habitat for wildlife viewing, and opportunities for environmental and farm education (see Detail 1 and Detail 2 on pages B14 and B16, respectively) create added incentive for community support in achieving the economic, environmental, and social goals of the project.

Centralized Activity
The main entrance and parking area located on Pleasant Hill Rd concentrate group activity where access is the easiest and where it will have minimal impact on habitat areas. This space is also ideal for CSA members to pickup their weekly shares. The proposed buildings and lawn space lend themselves to a wide range of group activities, from weddings and reunions to farmer’s markets and educational programming.

The other area of concentrated activity on the site is the farm complex. A separate entrance, additional farm structures, and a paddock and pasture network support a profitable local livestock business. Views from site’s central hill and the path network create opportunities for visitors to enjoy a pastoral aesthetic that connects to the region’s history. Encouraging interaction between visitors and the farmers also encourages education and awareness related to relevant farming issues in a rapidly developing area.
