Site Analysis

Site here!

Beijing Forestry University locates in Haidian District, north part of Beijing. And our site lies in school’s dependents’ area, which next to basketball court.

Site Analysis Cont.

Since the site was set between two residential buildings, it function as both front and back garden, which provide a green space for the tenements. This site was made for rest, relaxation and sport area. The dependents’ district has been here for about 20 years.

53.4 ft

223.1 ft

Total Square: 0.273 acre

Site Analysis Cont.

Depends on soil test, the site :

• has relative low levels of Iron and Magnesium. • needs a boost in Nitrogen and Potassium • is too moisture and compact in some area

Soil Test

Site Condition Recommendations

Site Analysis Cont.

TURF AREA

• 2-3lbs. of Nitrogen per 1000sq/ft.

• 3lbs. Potassium per 1000sq/ft.

• A 5 step weed control and fertilizer program

POOR DRAINAGE & LOW SPOTS

Install extra drains beneath the soil surface where the soil is

too moisture and make proper slope to avoid water gathering in

low spots.


Site Analysis Cont.

DEAD PLANT MATERIAL & PLANT OUT OF SHAPE REMOVAL

Removing the dead or damaged plants and replaced with

new material. Some plants lost ornamental function due to their

unpleasant shape.

TRANSPLANT WITHIN THE SITE

Some plants are still in good condition but grow in improper

places or against design purpose. Transplant those to make room

for a turf area, so that kids can spare their time on this site.

Site Analysis Cont.

INTRODUC NEW PLANTS FOR SEASONAL APPERANCE

Introduce some new species into the site so that every season

here comes out flower of the seasonal.

WIRES REMOVAL & NEGOTIATION WITH NEIBOURS

Residents here install wires between trees or branches as

clothes line. It will girdle the tree to death as the tree grows.

Therefore, we will negotiate with neighbors, convincing them to

give up their clothesline and promising them there will be a better

place for them to dry their clothes.

Problem Management

Treat Plan: Spray pesticide to prevent trunk and foliar damage

Snail Damage

Problem Management

Treat Plan: Remove all the volunteer trees since space, nutrient, light are limited in those places.

Dead Plant

Cont.

Problem Management

Treat Plan: Remove all the volunteer trees since space, nutrient, light are

limited in those places.

Volunteer Plant

Cont.

Treat Plan: Suckers will compete with tree for nutrient and water, so they should be removed to make sure the vigorous growth of tree

Problem Management

Sucker

Cont.

Treat Plan: Some watersprout should be pruned since they keep the light away from the foliar inside. The best time to remove watersprout is September to March when tree structure is much more clear without foliar.

Problem Management

Water Sprout

Cont.

Chewing Insects Spray insecticide during

the summer season to prevent their damage

Problem Management

Cont.

Treat Plan: Replace these plants with proper turf to make the lawn uniform. Potential hazard to children because of their thorns.

Problem Management

Thorn Hazard

Cont.

Treat Plan: Fill and level up ground then plant turf on it. Holes are potential hazard to pedestrian.

Problem Management

Holes

Cont.

Treat Plan: Iris should be plant at the vacuum place to form a uniform plant hedge.

Problem Management Vacuum

of Plant

Cont.

Treat Plan: Spray insecticide when aphids outbreak occur.

Problem Management

Aphids Damage

Cont.

Treat Plan: Insect lie eggs on the plant and the caterpillars eat the leaf . Proper insecticide should be used to kill the insect and their caterpillar.

Problem Management

Insect Damage

Cont.

Treat Plan: Turf under the tree cannot receive enough sunlight and they cannot tolerate shade stress. Cover mulches instead of turf around tree will solve this problem

Problem Management

Shade Problem

Cont.

Treat Plan: Further investigation should be conducted to identify the exact insect and proper insecticide should be used to kill the insect

Problem Management

Evergreen Trees

• Pruning in late February to early March. Least amount of stress

• Trimming out dead, diseased and damaged part of trees. • Some stubs need to be pruned
