Melaleuca Forest Survey of the N.T.

1. Introduction

Funding was obtained from the National Forestry Inventory to undertake a survey of the Melaleuca forests in the Northern Territory. The N.F.I. definition of forest is 'woody vegetation, usually with a single stem, having a mature or potentially mature stand height exceeding five metres with existing or potential projective cover of overstorey strata about equal to or greater than 30% '. This definition was extended to include woodlands with a projective cover of 10-30% during the period of survey.

Definable Melaleuca communities with a potential pfc of 10% or greater were floristically assessed. Melaleuca communities with a pfc greater than 30% were assessed for floristics, stand attributes and wood volumes. 412 floristic sites and 120 wood volume sites were assessed across the northern part of the N.T. Mapped area extends from the northern coast to approximately 18 degrees south latitude. Approximately 2.5 man years was invested in the project.

The following information pertains to the data-bases created for the Melaleuca survey and includes brief notes on methodologies. Notes on methodology are also contained with the explanation of data-base attributes. A more detailed synthesis of the data is proposed in the future.

2. Project outline:

There were three main components to the project. These will be outlined in more detail later.

1. Mapping the distribution of Melaleuca Forests. April-July 1993

2. Field survey. Measurement of floristic and stand correlates. July-December 1993

3. Database construction, Analysis, map production and report. January-July 1994

2.1 Distribution and Classification

Objective:

2.1.1 To produce 1:250 000 topographic maps with mapped boundaries of significant Melaleuca communities (compilation scale at 1;100 000).

2.1.2 A classification of the communities for both floristics and stand characteristics

MELADATA.DAT-Info file (plot site data) MELACOMM.DAT- mapping unit and volume figures

2.1.3 Digital output (ARC/INFO) of map boundaries with related attribute files MELALEUCA-NT Polygon cover

MELASITE.PAT Point cover with geo-referenced sites.

2.1.4 A file containing information as to reliability of the mapping to be stored on ARC/INFO (MELARELIB.DAT).

Methods:

2.1.1 Mapping distribution

Melaleuca community boundaries were interpreted predominantly from aerial photography. Compilation scale was 1:100 000. Production scale of mapping is at 1:250 000. The quality of the aerial photography varied. Black & white and colour photography was used at various scales from 1:25 000 to 1:80 000 depending on availability. Landsat TM scenes at 1:100 000 and 1:250 000 were used where photography was unavailable. Age of the photography varied. Areas of forestry potential, mostly occurring in or near the major floodplains of the N.T were interpretated from the most recent photography or imagery available (ie Kakadu NP was interpreted from 1991 colour 1:25 000, Arnhemland 1:50 000, 1984 colour photography). However some of the inland areas were interpreted from high level 1:80 000 b/w photography which was the only available material.

Interpretation was transferred directly onto 1:100 000 topographic maps. In the case of streamline forests or narrow fringing forests (ie with very large lineal extents and relatively small widths) single lines were draw on the topographic maps. All areas with large enough discrete areas (0.4 ha+ on the ground) were record as polygons. Not all communities mapped were of forestry significance. Also, because of the narrow nature of the streamline forests(particularly towards there sources and scale of interpretative photography and mapping, some areas of creeklines containing Melaleuca communities will not have been mapped. ( Most coastal and sub-coastal creeklines contain M.viridflora open-forest to woodland ). Conversely because of the high level of the photography in some regions areas of forest discernable on the photographs may not prove to be pure Melaleuca forests. These forests however are of interest as communities and floristically but are not utilisable in the forestry sense.

2.1.2 Classification

A preliminary classification based on topographic postion, density, height and local experience was attributed to line work and polygons. This was re-intepreted following field-work and community definition.

2.1.3 Digital ARC/INFO coverage.

Once the final mapping boundaries are determined, for each 1 : 100 000 topographic map, linework was digitized into ARC/INFO system. The preliminary classification was incorporated on the arcs as arc-ids. The streamline forests (ie arcs only) were buffered to form polygons and arc-ids transferred to the polygons. (A buffer width was determined for each community type based on average widths of the streamlines).

Community(RECODE1) 3,4,6,9,11 1,2,7,8,17 16

Buffer Width 10 metres 20 metres 30 Metres

3

Polygons were digitized in and arc-ids transferred to the polygons. As the covers were fairly large, the problem of 10,000 arcs in a polygon was encountered such that once the digitizing was complete the cover needed to be split before polygonization occurred. The separate covers were then brought together again. The final cover is MELALEUCA-NT and is in lamberts projection. The vegetation community relating to the mapping is stored as attribute recode1.

2.1.4 Reliability of mapping.

For each 1:100 000 map sheet a file containing information on the reliability and accuracy of the mapping is provided. The MELARELffi.DAT file contains the following information.

Field survey was undertaken from July to December, 1993. Floristic sites and where appropriate wood transects were assessed. Access was by vehicle. The mapping patterns were rechecked by light aircraft across the main floodplain regions.

1. Vegetation attributes

2.2.1. Floristic survey

Objectives:

Methods:

Floristic information.

To adequately assess the resource for floristic and structural characteristics and determine discrete communities.

To adequately assess the the geographic range and types of the Melaleuca forests.

To assess the present status,threats and conservation of the Melaleuca forests. (condition & dynamics).

Plots were located according to the initial interpretation and distribution map and reassessed in light of subsequent field survey. Plot location was designed to cover the community variation and geographic range of the perceived Melaleuca communities.

4

Floristic plots were assessed by a 20m by 20m quadrat. At each plot, data was collected on species abundance(basal area/percent foliage cover sensu Carnahan 197 6) as they occur in the upper, middle, and ground layers. Where possible full floristic lists were compiled for each plot.

Lifeform information was recorded(cover and height) in 15 generalised categories. (see attachment 2 and floristic field sheet. Attachment 3), together with dominant lifeform, total cover and average height for each stratum.

Environmental information noted at each plot includes landform element and pattern slope,aspect,rock outcrop%,bare ground(%), water depth etc.

2.2.2 Site specific variables

2.3 Wood transects

2.3.1 Wood attributes/transect variables

Objectives:

1. To estimate possible gross bole volume of Melaleuca forests by community type.

2.To determine merchantable volumes for Melaleuca forests with utilisable potential.

Method: Wood volume and stand attribute information was collected from transects adjacent to the floristic plots when appropriate. Not all forest types were regarded as of forestry potential. Minimum plotsize was generally 0.2 hectares. Two transects 100 metres long by 10 metres wide or one transect 200 metres long by 10 metres wide was assessed. The raw data was not sent to NFI but is stored at CCNT, Darwin.(see appendix)

The following information was collected at each site.

Table of frequencies by height classes of seedlings and regeneration. Counts made 1 metre either side of the centreline of the transect. Plot size 0.04 hectare. Regeneration was classed as all melaleuca saplings with a dbhob of 2cm or less.

Trees with a diameter 2-29.99cm DBHOB arranged in 5 em diameter classes (2<5cm, 5<10cm etc.) and measured for heights. Dead trees within these diameter classes were also measured. Trees other than Melaleucas were not measured. Possible small pole lengths (not bole heights) were determined as trees were measured.

All trees with a dbhob of 30 em or greater were measured for wood volumes. An average bole volume was determined for trees less than 30cm dbhob. The wood transect data was

Diameter breast height over bark measured at 1.3 metres above ground level.

Average thickness from four measurements around the trunk.

Height in metres to tip of bole (first major crown break). These heights were used to determine gross bole volume irrespective of log class.

Merchantable height of the tree in metres. These heights used to determine merchantable heights within each log class. In the case of pulp logs the merchantable height in most instances was equivalent to bole height.

Stump height in metres.

Length of sawlog in metres. Length of pulplog in metres. Length of pole log.

Classification of the tree. Trees were classified in the field into utilisation classes. These classes were then used to determine the volumes.

1=sawlog only 2=pole log only 3=sawlog and pole log 4=pulp log 5=sawlog and pulp log 6=pole and pulp log ?=unmerchantable 8=missing/lost

Defect categories. These were appraised visually in the field with defect codes the same as those used for a major inventory of the NT forests undertaken by the Forestry section of the NT from 1960-1974. The visual assessment of these former surveys was tested and evaluated from log measurement data taken from felled trees. In some instances a particular tree may have had more than one defect. However the major defect affecting its utilisation was the one recorded.

The following categories were used.

1 =nil defect

2=Blown top 3=Ant infected 4=Fire damaged

14

5=Buffalo/cattle damage (ie exposed roots, bark removal etc) 6=Twisted (spiral grain) 7=Bowed or bent 8=Multi-stemmed 9=Dying lO=Recently dead 11=Long dead 12=Salt intrusion 13=Missing

2.3.2 Criteria:Log measurement (For trees with DBHOB > 30cm)

Sawlogs

Pole logs

Small pole logs

Minimum small (top) end diameter=20cm Minimum log length= 2.4 metres Minimum big (DBH) end diameter= 30cm

Minimum small end diameter= 10cm DBHOB Minimum length = 3 metres Minimum big (DBH) end diameter = 30cm

Minimum diameters between 5-10 em dbhob.

Defect and log classification codes listed above with wood variables. Trees were assessed in the field using the above criteria.

2.3.3 Volume data

Volumes were determined using a volume equation. Areas initially discemable and able to be mapped from the aerial photography were used/can be used for volume calculations. (ie many of the streamline communities were too narrow to be of forestry potential). The main cover MELALEUCA-NT contains an polygon attribute called utilvol which if Yes means that the polygon was used to determine areas on which total volumes were determined. Of the buffered linework only RECODE1 = 16 communities (major rivers­bank forest and springs) were used in volume calculations. Volumes for trees with dbhob of 30 centimetres or greater were determined with the criteria as described previously. Small pole volumes were determined for trees with a dbhob less than 30 centimetres. Gross bole volumes were also determined to get an estimate of stand volumes.

Volume equation

The equation and constants were taken from Archers Thesis 'Tree Volume Models for Tropical Broadleaved Forests,1977' (Archer 1977). These volume models were determined using the field inventory and log assessment information collected during the forest

15

inventories undertaken between 1960 and 1974 in Top End open-forests. There were three sets of constants determined for Melaleuca sps., pertaining to different regions of the Territory. The constants for Murgenella were used due to the proximity of the region to the larger Melaleuca forest stands (ie coastal and sub-coastal regions). Most data was collected for M. leucadendra, M. viridiflora, M. cajuputi and M. argentea which are the main trees of forestry significance.

The volume equation is of the form:

where V = Volume in cubic metres

D =Diameter under bark**

b0 = -0.00366

bl = 0.000084725

b2 = 2.0364

b3 = 0.61603

** In the thesis it is not explained whether the diameter category is dbhob or dub. To be cautious we have used 'D' as diameter under bark which may result in an approximate 15% under estimate of volume. (Average bark thickness of M.leuca, M. caju and M.viri for dbhob >30 em is 3.2 em. If this is applied to the mean diameter of 41.5 and mean log length of 9 metres the under estimate of log volume is in the order off 15%). ** Bark thickness varied considerable for trees of the same species and diameters.

3.1 Mapping Units/Community forest types

TWINS PAN (Hill 1979) and P ATN (Bel bin 1987) were used to help deliniate floristic communities. The following file contains summary information relating the mapping with the melaleuca forest types and volumes, heights etc. It is the synthesis of data from most other data files.

Most of the merchantable volume is made up of pulp log material and pole. The amount of utilisable saw-log material was fairly small even though gross stand bole volumes was high. The largest amount of saw-log material occurs in the large riparian and spring forests (recode1 = 16) which contained the biggest trees. However the areas used for volume figures for community 16 were from buffered line-work so the figures for this community should be treated with caution. Also the figures have been biased upward by the presence of a few very large trees (dbhob 1.2 metres and greater) which are the exception rather than the rule. Average diameter for trees greater than 30cm dbhob is 41.5cm dbhob. If you feel it appropriate I can redo the figures for this community by removing the largest trees. This may provide a more rigorous value.

Pole volumes per hectare for each diameter class. Calculated from mean pole length(not bole length) per dia.class measured in the field (l\1ELASTOCK.DAT) * midpoint dbhob of dia.class * stems/hectare per dia. class. The length of possible small pole material was recorded in the field for each diameter class as the tree was measured. These values are a measure of possible gross small pole volumes in a stand. It was determined assuming all trees in a stand were utilisable which is not the case. The following utilisable volumes were determined by multiplying the pole volumes by the percentage of utilisable stems in each dia. class. The number of utilisable stems was determined from the number of pole length measurements recorded in the field (ie number of scores) for a particular diameter class versus the total number of stems in any particular diameter class.

An estimate of total standing bole volume of live trees per hectare from 2<30cm dbhob.

This datafile contains stocking figures by 10 centimetre diameter classes and 5 metre height classes. The number of stems falling into each category on the 20 by 20 metre vegetation plot were recorded. This information was recorded to provide stocking figures for plot sites were a forest transect was not assessed ( ie on M.minutifolia low open woodlands which were not of forestry interest due to small diameters of most trees). The information was recorded in a cross table with diameter classes as one axis and height classes as the other.
