2 RESULTS AND DISCUSSION CONTENTINTRODUCTIONOBJECTIVESMATERIALS AND METHODSRESULTS AND DISCUSSIONCONCLUSIONREFERENCES
3 INTRODUCTIONA combination of natural resource factors in a forest created attractions to recreation activities to peoples (Hammit and Cole, 1998).Hence, persistent physical activities in the forest caused undesirable and physical changes to the natural resources of a forest (soil condition and vegetation health).Most of the impacts were started from a trail used to access the recreation area.
4 INTRODUCTIONExcessive trail-related impacts to vegetation, soil, and wildlife or water quality may affect the comfort and recreational experience of visitors.In order to mitigate the problem of impacts on the natural resources along the trails, related management actions need to be taken immediately including monitoring the areas systematically and continuously and focus on the impacted areas to avoid the occurrence of an adverse situation.
5 OBJECTIVESTo quantify the physical changes on soil and composition of plant species.To compares the changes those occur between parts of lowland and types of physical changes.
6 STUDY AREA Ulu Bendul Recreational Forest, Negeri Sembilan MATERIALS AND METHODSSTUDY AREAUlu Bendul Recreational Forest, Negeri SembilanCompartments 45 and 52 in Angsi Forest Reserved Negeri SembilanTotal area : 6.47 haHeight : 825 meters a.s.lForest type :Lowland Dipterocarp Forest02° 42´ 67´´ N latitude 102° 03´ 93´´ E longitude
7 COMPARISON OF USED AND UNUSED SITES MATERIALS AND METHODSRESEARCH DESIGNDESCRIPTIVE SURVEYCOMPARISON OF USED AND UNUSED SITES
8 Research DesignDESCRIPTIVE SURVEYEstimates and measurements are taken on sites to access current resource conditions (Rochefort and Swinney, 2000)Physical changes to soil : measurements on expansion of trail width, soil compaction, and presence of gullies.Plant composition : identification and estimation of type of plant species.
9 Systematic Observation Research DesignDESCRIPTIVE SURVEYSystematic Observationhiking trails in lowland part of Gunung Angsi were divided into 3 sub-parts ;lower sub-part (<100 m)middle sub-part (100 – 200 m)upper sub-part (200 – 300 m)The observation and measurement were conducted on every Saturday started at 8.30 a.m in three consecutive weeks in the month of February 2008Three impacted plotswere built ateach sub-parts
10 COMPARISON OF USED AND UNUSED SITES Research DesignCOMPARISON OF USED AND UNUSED SITESMeasurements were taken on recreation sites (impacted plot) and nearby undisturbed site which is a control plot (Hall and Kuss, 1989).Control plots were built at each sub-part with three replications of impacted plots (beside the trail).The plant species that present in control plot were compared to the impacted plot in order to determine whether there are appearance of exotics species and type of species survived.Simple random samplingidentify the plant composition by selecting plant species in control plot randomly

12 DATA ANALYSIS Descriptive Analysis Correlation Analysis MATERIALS AND METHODSDATA ANALYSISDescriptive Analysisto get frequencies, maximum and minimum value, mean, and standard deviation to evaluate the physical changes on soil surfaceCorrelation Analysisto seek for a relationship between an expansion of trail with presence of gully and soil compaction.Analysis of Variance (ANOVA)to test the significant difference of all sub-parts of lowland part of Gunung Angsi with all types of physical changes on soil.
14 Analysis of variance for lowland part of Gunung Angsi RESULTS AND DISCUSSIONSAnalysis of variance for lowland part of Gunung AngsiUPPERMIDDLELOWERFP-ValueExpansion of trail width1.003a0.904ab2.167c10.7130.000Presence of gullies0.00a7.89ab41.89c48.520Soil compaction3.378b2.311a2.900ab5.8480.009
16 RESULTS AND DISCUSSIONS SOIL COMPACTIONThere were no changes occur on value of soil compaction within three weeks in plot 2 in upper sub-part and plot 3 in middle sub-part of lowland.The most compacted soil is in plot 3 in the upper sub-part with 4.2 g/cm2 followed by plot 1 in lower sub-part with 4.0 g/cm2.However, soil in plot 2 in middle sub-part was the most uncompacted area with only 2.2 g/cm2 of compaction.
18 RESULTS AND DISCUSSIONS EXPANSION OF TRAIL WIDTHThe highest total increment of trail expansion within 3 weeks are plot 1 in upper sub-part and plot 2 in middle sub-part with 0.7 meters.There are no enlargement of trail width occurred in plot 1 in middle sub-part within 3 weeks.From field observation, there are two different paths in plot 3 in the lower sub-part. It has been divided by several shrub and there is a big rock has blocked one of the path. This situation leads to the creation of another trail. After being used continuously, it resulted in expanding trail width reached almost 4.0 meters length.
21 RESULTS AND DISCUSSIONS PRESENCE OF GULLYGullies presentations were absent in plot 1 and plot 3 in middle sub-part and upper sub-part of lowland of Gunung Angsi.There were gullies presentations in all plots in lower sub-part.The deepest gully was in plot 2 in lower sub-part with 60 cm depth.The highest increment of deepness of gully within 3 weeks is at plot 2 in lower sub-part with 10 cm.In connecting with the appearance of gully erosion, trail expansion usually takes place.It is a natural tendency of users to walk along the trail edge rather than trail tread to avoid gully erosion.

23 RESULTS AND DISCUSSIONS Correlation of expansion of trail width with presence of gullies and soil compaction
25 RESULTS AND DISCUSSIONS PLANT COMPOSITIONThere were no species left in plot 3 in lower sub-partDue to the trail expansion that damaged the vegetation either by trampling or other reactions by users (e.g: bend or shake the plants).Only one species survived in plot 3 in upper sub-partThis happen as a result of the high degree of compaction (4.2 g/cm2) a tough condition for plant to survive.
26 CONCLUSIONLower sub-part of lowland has changed quite significantly that can be seen on the presence of gullies and the expansion of trail. Plot 3 in the lower sub-part of lowland has experienced soil degradation including declination of plant composition.The upper sub-part of lowland is the most compacted area and this lead to the poor establishment of plant where there are about six out of ten species left in impacted plots.
