Several studies had been done to proof that human needs an ecological sustainability to survive, and the nature also needs human’s changes of behaviors to sustain its stability. The three studies share some idea toward a sustainable goal. Groenewegen (2008,) suggested that the green space in living area affect human health and percep
-tion of the safety in community, so they will be more likely to participate and contribute

Why Owls?
The area we currently live was once called the Big Grove. It was where the oaks and other giant trees covering in thousands of squarefeet land. Tying the animals from dif-ferent regions to come together. Since the land development was established, the reduction of the forest land progressed severely. Shown above are the diagrams com-paring the Big Grove and its remaining be-tween 1821 and 1999. Less than two centuries, more than 70% of the precious woodland was turned into housing development, farmland, and urban sprawl.
This is why we should at least try to save what is left for us to cheerish. The Busey Woods, a part of the remains, are in trouble with the construction dump and the raids of invasive species over the year. Now it is time to reestablish the infrastructure of the forest. Perhaps in the future, this part of restoration can weave the Big Grove back to the geogra-phy as another fabric along with the urban and agricultural blanket across Urbana-Champaign landscape.
Owls, especially Eastern Screech Owls are well known for controlling the populations of small mammals, reptiles, and insects. We have so much rodent problem in the household partially because the lacking of the predator.
The insects became the problem recently also due to the lack of birds in the region. The aphids outbreak in 2009 and the japanese beetle swarm in 2010 were also to blame. In-troducing the owls back to the urban fabric will help preventing these outbreaks to reoc-cur.

Habitat
The trail acts as a conduit that carry people across the forest
The roots of the tree act as a filter for the runoff from the street
The hole in an oak tree acts as a habitat for the owl to live in
The vernal ponds act as the sink that collects water from rain
The ground filled with leaves are the source of nutrient for wild flowers
Goals and ObjectivesMission Statement Enhance the ecosystem around Busey Woods, complete its infrastructure by creating habitats for Oaks which will help remove the undesirable invasive species, and invite the species that create rich
-
ness to the ecosystem such as screech owl while find support from community group to help sustain nature.Goals and Objectives1. Protect large canopy trees such as oaks and improve its reproduction availability 1.1 Clear off invasive species such as maple trees and honeysuckles along the forest 1.2 Introduce large tree species that help stabilize the soil and improve the forest structure 1.3 Protect the area 50 feet radius around existing oak trees from any soil disturbance 1.4 Let some part of the forest develop naturally to accommodate species that are adjusted to the current woodland conditions
2. Increase the biodiversity and provide appropriate habitats for wildlife and sustain them 2.1 Put the bird houses on the trees in the woods to accommodate birds 2.2 Introduce wild flower species back to the site 2.3 Improve buffering with vegetation around the site to prevent road kills. 2.4 Locate maintenance area on site 2.5 Substitute certain area of Kentucky blue grass to alternative groundcovers
3. Improve the educational function for residents and visitors 3.1 Extend walking trails above ground to allow drainage system 3.2 Reserve some part of the woods undisturbed 3.3 Provide visual access and information about ecology and sustainability
At the Edge This part of the forest has the closest access to the outside street, hence can create noise pollution and cause roadkills to wildlife. It needs buffer.
Invasives Once a gigantic grove, now an oasis. Busey Woods tries its hardest to sustain its quality, yet it struggles with invasive species such as honeysuckles and maples.
Glory games The horse stable and field might be an interesting sports, but it barred the park from the woods with metal fence. The noises from the races can also be pollutant to wildlife
Transition The area acts as a transitional zones between the park and the residences. It also has a bus stop and a small plaza to offer some fun chances that draw people to the park.
Hospital The proximity between Carles Hospital and the park offer the opportunities for patient and faculty members to come and take a relaxing time in nature
Salt Fork The salt fork is the creek that channelled the water from Lake of the Woods to Kickapoo. For this fork, the water quality is very impor-tant.
Nature Center Amita Purves Nature Center are the sources of information for Busey Woods. It is also a gathering area for people who want to explore the wilderness
Untamed Corridor The road that goes along the perimeter of the park is not very well kept. Requiring more effort to go to Busey Woods.
Weak Connections This transitional area has only one walking trail connecting Crystal Lake Park to Busey Woods. The connec-tion needs improvement.
Neighborhood The neighborhood can benefit a lot from the park and the woods. They will also be an important key to allow changes and development to these green spaces
The Crystal Lake Pond This retention pond offers water recreation and scenery, and the openspace around it offers some active recreations.
LEGEND
Oaks and Flowers The landcover analysis suggests that the area are compatible to grow oaks and wildflower to support the forest structure and biodiver-sity.
Parking lots The parking lot and the driveways in the park takes to much space, making runoff very difficult.
Bad Views The views off the fence here is quite unpleasant. It requires some visual tactics. The fence itself blends fine.

Aside from regular vegeta-tion, the oaks are added in crystal lake park, blending in for community uses
The buildings remain the same, apart from the addition of the maintenance building in Busey Woods
Circulations are adjusted the most in front of Anita Purves Nature Center, to be a gate-way to explore nature
The channel of water remains the same in this design
Alternate groundcovers are encouraged to be used across Crystal Lake Park in this design
This is the primary site boundary of habitat that can be expanded in the future
Topography in this design is only subtly changed for drainage purposes
The site remains woven in the urban fabric of Urbana-Champaign

The site as exists. Con-taminated yet it is the oasis of wildlife
The habitat for owls and oak is prepared on the northern part. The geo-process begins
Create a strong buffer for the site and start add in the adaptables on the east side
Create the oaks and owls habitat on the wetland area
Finish the construction dump site, turning it into the area for tough, adaptable plants

Intergration is the project that combines the existing of nature and human together. The intention of the design is to restore a fraction of what once was the great oak grove. By returning the oaks into its home, the animals will come back and the ecosystem will start to flourish again. Another focus species is the eastern screech owl. By bringing back the oaks, the terrance of the forest open up enough to allow the owls to exist. The owls would also get rid of rodent problem around the city. Finally, human is the important part of this design. By inviting people into the education and exposure of nature, human tend to grow to love the nature and thus try to safe it. This is the reason why we provide the educational area for people in the north east corner of Crystal Lake Park.

At the Edge The addition of buffer species such as spicebush helps protect the wildlife from crossing. It also creates the visual buffer from people inside to see the street
Invasives Honeysuckles and maples will be removed to create a chance for the oaks to grow and to create the hunting ground for different kinds of animals including owls.
Transition The transition remains the same, but the parking lots are changed into grasscrete to help reduce to stormwater runoff.
Hospital The improved social gather-ing area and the introduced passive recreational area helps the patients and faculty members of the hospital restore their mental fatigue.
Nature Center The concept of the nature center expands over this entire space. By adding the multi-purpose field for camping and other activities, people from the community can get closer to nature
Neighborhood Passive recreational areas can be used by the residents of the neighborhood to restore their mental fatigue and improve their physical health. It can introduce them more to nature
The Crystal Lake Pond The pond can be enjoyed more on the other side from adding the meander path and ornamental trees along the way.
Oaks and Flowers The oaks are added into the forest to re-establish the forest infrastructure, improving it to be a hunting ground of owls and other birds Parking lots
The parking lot are changed to grasscrete, and there is the bioswale for best management practice.

Connection to the cemetery are made for occasional visitor, but not for all. It acts as a filter for this woods.
Maintenance hut located near the road has both access to the urban area and to the forest.
Habitat area for oaks and owls. Wild flowers are in full bloom in early spring.
The power row, being stark and bold, can enhance the way finding experience during a visit in Busey Woods
The oak saplings regrowing after the construction waste are moderated with the adaptable species
Theon the ridge into the South Pond during fall season can be quite attractive

The open space in front of the nature center can be used multi-purposely, ranging from outdoor class, camping, to sports
The closed area around this space gives out the private feeling, yet very ac-cessible to community.
The temporary parking becomes an open space when not used by vehicles.
