Studies on Restoration of Forest - Floor Vegetation Devastated by Recreational Trampling - A Case Study of the Mt . Kwanak Region -

Koo Kyoon Oh 한국산림과학회 1993 한국산림과학회지 Vol.82 No.1

For elucidating effective methods of restoration of forest recreational sites where management goals are maintaining naturalness and conserving natural ecosystem, seeding, fertilization and soil surface treatment were used for four years at the devastated forest-floor. And seeding treatment was used for 2 years at an artificial bare ground for selecting tree species suitable for forest-floor revegetation. For restoration of forest-floor vegetation, factorial experiment was used with a split plot design (main plot : fertilization, subplot : soil surface×seeding) and a randomized complete block design(fertilization × seeding) at the Kwanaksan Aboretum, Anyang, Kyonggido. For selection of tree species suitable for forest-floor revegetation, shading, soil surface softening and straw-mat mulching treatment were used with a randomized complete block design using 19 native tree species in the same factorial design . Results were summarized as follows 1. Soil surface softening with tipping and ripping and straw-mat mulching(70% coverage) treatment was effective on germination, survival and growth of seeded vegetation at devastated forest -floor. Expecially, straw-mat mulching treatment was effective on soil surface stabilization and seedling`s survival at eroded soil surface, while complete soil surface softening treatment was effective on germination, survival and early growth of tree species(Cornus controversa, Euonymus sieboldianus, etc. ) of late-successional seres. 2. Introducing seeds of native species(Zanthoxylum schnifolium, Styrax japonica, etc.) of pioneer or early-successional seres, with good growth capability in barren soil was effective on rapid restoration in devastated forest-floor with its soil surface previously compacted and its surviving seeds washed away. 3. When the seeding and straw-mat mulching after partial soil surface softening with tipping and ripping treatment were employed, it took about three years to restore the devastated forest-floor. Where surface erosion had been undertaken for an extended period of time and where naturally surviving seeds of native species had been washed away. 4. Softening treatment of soil surface was effective for about two years, and seeding and soil surface treatment increased number of seelings and improved soil surface environment through fixing of movement of the fallen leaves. 5. The effect of Lespedeza maximowiczii used as a nitrogen fixing plant was not observed due to severe surface erosion after seeding operations. Direct seeding and subsequent growth of Quercus acutissima were not noticed due to vandalism by widelife as well as man. 6. Fertilizing effect was not oberserved, mainly due to seedling exposure and poor physical condition including soil surface erosion, low soil water potential and drought, etc, at the field experimental site. However, application of nitrogen and phosphate fertilizers was effective on seedling survival of the species in late-successional seres, while lime application, adversely affected the seedling survival. 7. Native species suitable for restoration of bareland under 75% shading in central part of Korea are Styraz japonica, Styrax obassia. Smilax china, Callicarpa japonica, Stephtznaradra incise, Viburnum dilatatum for. pilosulm, Magnolia sieboldii, Cornus kousa, Celastrus orbiculata, etc. Especially, Magnolia sieboldii, Stephanandra incisa and Styrax obassia were tolerant for forest-floor with hardened soil surface and Callicarpa japonica, Viburnum dilatatum for. pilosulm, Euonymus sieboldianus and Philadelphus schrerkii suitable for softened soil surface with straw-mat Philadelphus schrenkii suitable for softened soil surface with straw-mat mulching. 8. The seeds of Styrax obassia, Styrax japonica, Viburnum dilatatum for. pilasulm, Smilax china and Stephartandra incisa needed to break seed dormancy to accelerate germination.

The estimated number of visitors for entering the park through survey points was 1,864,623, the people just passing through the park by a vehicle was 832,070 and visitors using others than survey points was 93,231. There was a 2.8 times of difference in the number of visitors with a ratio of 74% of total visitors in Jeungsimsa district and 26% of that in Wonhyosa district. The result showed that the ratio of visitors who were headed for Jungmeorijae from Jeungsimsa district or Wonhyosa district was 34.1% of total visitors and 30.3% of these visitors were heading for the summit. The ratio of visitors who were heading for the summit such as Jangbuljae, Ipseokdae, Seoseokdae, Gyubong, etc. of Mudeungsan Provincial Park was 21.1% of total visitors.

낙남정맥 마루금 일대의 식생구조 특성1a

오구균 ( Koo Kyoon Oh ),강현미 ( Hyun Mi Kang ),박석곤 ( Seok Gon Park ) 한국환경생태학회 2014 한국환경생태학회지 Vol.28 No.6

낙남정맥 마루금 일대의 식생상황을 파악하기 위해 환경조건과 인위적 영향을 고려하여 중점조사지 6개 지역(길마재, 무량산, 여항산, 무학산, 천주산, 신어산)을 선정하여 방형구 132개소(면적 100㎡)를 설치하여 출현수종 및 주요 환경인자를 조사해 식생구조 특성을 분석하였다. TWINSPAN기법으로 분리된 군락은 신갈나무-굴참나무군락, 소나무-떡갈나무군락, 신갈나무-소나무군락, 편백림, 소나무-곰솔군락, 잣나무림, 철쭉재배품종-참싸리림이었다. 소나무-떡갈나무군락, 신갈나무-소나무군락, 소나무-곰솔군락은 하층에 낙엽성 참나무류의 세력이 강해 낙엽성 참나무류로의 식생천이가 예상된다. 편백림과 잣나무림, 철쭉재배품종-참싸리림은 인위적으로 조성된 인공림으로 조림수종의 우점도가 높아 당분간 현상태로 유지될 것이다. 낙남정맥의 식생은 대부분 2차림이거나 임목생산과 사방녹화를 위해 조성된 인공림이 었다. 특히, 산정상부와 고지대는 대부분 신갈나무, 떡갈나무 등의 낙엽성 참나무류가 우점하거나 일부 소나무군락은 낙엽성 참나무류와의 세력경쟁을 벌이고 있었다. 반면, 저지대나 도시와 인접해 있는 지역은 곰솔, 편백, 잣나무, 철쭉재배품종 등이 식재되어 인위적인 간섭이 심한 편이었다. To figure out the vegetation situation in the ridge of the Naknam-Jeongmaek, six intensive survey sites were selected considering environmental factors and human interferences, 132 quadrats (area 100㎡) were installed to survey appearing species of trees and major environmental factors, and the characteristics of vegetation structures were analyzed. The surveyed plots were divided into six groups according to the analysis of classification by TWINSPAN; Quercus mongolica-Q. variabilis community, Pinus densiflora-Q. dentata community, Chamaecyparis obtusa community, Q. mongolica-P. densiflora community, P. densiflora-P. thunbergii community, P. koraiensis community, Rhododendron spp.-Lespedeza cyrtobotrya community. P. densiflora-Q. dentata community, Q. mongolica-P. densiflora community, and P. densiflora-P. thunbergii community are expected to be succeeded by deciduous oaks because the power of deciduous oaks is strong in their lower layer. C. obtusa community, P. densiflora community, and Rhododendron spp.-L.cyrtobotrya community are artificial forests that were artificially formed and are expected to be maintained in the current state for some time because the dominance value of planted species of trees is high. Most vegetations in Naknam-Jeongmaek were secondary forests or artificial forests formed for forest tree production and forestation for erosion control. In particular the top regions and hilly sections of the mountain were mostly dominated by deciduous oaks such as Q. mongolica, Q. variabilis showed some P. densiflora community competing with deciduous oaks. On the other hand, low sections and regions adjacent to the city showed severe artificial interference since exotic species such as P. thunbergiil, C. obtusa, P. koraiensis, and Rhododendron spp. were planted.
