Potorous Tridactylus

ABSTRACT A population of the Northern Long-nosed Potoroo Potorous tridactylus tridactylus in Tyagarah Nature Reserve on the far north coast of New South Wales was first recorded in 1985. In 1992, a cage-trapping study captured 15 individuals in the central section of the reserve and the population was estimated at 80–90 individuals at that time. A subsequent cage-trapping study in 2004 captured four individuals in the southern section of the reserve, but further cage- and camera-trapping surveys in 2009 and 2012 failed to detect any individuals. Additional camera-trapping surveys between 2012 and 2015 and more intensive surveys between 2015 and 2016 also failed to detect any individuals. The lack of detections from targeted surveys over seven years between 2009 and 2016 suggests that the Tyagarah population of the subspecies has been lost. Reasons for this loss are unclear but may be due to a combination of factors including isolation of the reserve by urban development and highway upgrades, a lack of fire for 40 years, competition for food with the local population of the Australian Brush-turkey Alectura lathami, prolonged drought and possibly, predation by the Red Fox Vulpes vulpes and non-target effects of predator control programs.

Musical Practices

This paper draws on research conducted for over a decade on the musical cultures of the New South Wales Far North Coast, as a contribution to debates in geography and popular music studies on the links between music, place and articulations of cultural identities. Patterns of migration and economic restructuring over the last 20 years have transformed the Far North Coast region, with associated changes in the images conjured to describe the region – from those centred on dairying, fishing and sugar harvesting to those of a ‘lifestyle’ or ‘alternative’ region, with growth in employment in tourism, recreational services, ‘gourmet’ agricultural production, culinary delights, homewares retail and the arts. Music has been a constant presence in the region throughout generations, but became much more pronounced after significant counter-urban migrations to the area began in the 1970s. As music emerged as a unique part of the cultural mix of the region, it became much more diverse, was entangled in local politics, and in the transitions and tensions that have surrounded successive waves of new migrants – both domestic and international – to the region. This article discusses music as a social practice within the region that has played a part in shaping and reflecting evolving regional identities; but at the same time, music constitutes a set of activities that unsettle notions of ‘boundedness’ or ‘stable’ associations between place identities and music. I begin with debates about the links between music, place and identity, and the extent to which such associations are performative – constituted in an embodied fashion in the process of describing and enacting certain cultural discourses. Two broad trends are outlined here as ‘storylines’: one focused on constructions of music as ‘authentic’ that are linked to place identities, the second emphasises mobility of musical languages, and network metaphors for the repetition of musical practices across locations. Interpretations of musical practices on the Far North Coast hold these storylines in tension; one focused on ‘fixing’ musical practices in place, the other emphasizing the fluidity of ‘the region’ in a wider musical geography.

Shoot Mass

An experiment to examine the effect of tillage practice on yield, nodulation and nitrogen fixation of soybean in a podsolic soil on the far north coast of New South Wales is reported. Soybeans were sown into either a cultivated or no-tilled seedbed following pasture in 1983 and 1984, and following soybeans in 1984 and 1985. Results over the 3 seasons indicated substantially improved nodulation under no-tillage. The mean nodulation index (nodule mass as a percentage of shoot mass) was 4.5 for no-tillage soybean and 2.3 for the cultivated crops. Nitrogen fixation, assessed using the ureide technique, was higher in the no-tillage plots, especially during early plant growth, Plant growth and seed yield were increased by no-tillage in the wetter 1984 season; the reverse occurred in the other 2 less favourable years. Data on crop N, seed N, and fixed N (estimated by partitioning N accumulated by the crops during successive periods of growth, according to the relative ureide values) were combined to calculate N balances. Potential gains of soil N were greatest under the no-tilled soybeans (as much as 110 kg Nha; mean over all seasons was 80 kg Nha). The cultivated crops showed a maximum gain of 86 kg N/ha and an average gain of 30 kg N/ha. The data indicate that soybean has the potential to improve the N fertility of podsolic coastal soils, particularly when grown using no-tillage practices.

Barren Grounds

The population biology of the long-nosed potoroo (Potorous tridactylus) was investigated at Barren Grounds Nature Reserve and Budderoo National Park in the Southern Highlands of New South Wales (NSW). Both study areas are important conservation reserves for this threatened species, with a large gap north (~300 km) to the next known viable population on the mid-north coast of NSW at Mount Royal. Potoroos were live-trapped using bandicoot-sized cage traps, each set ~100 m apart along walking tracks and fire trails. Trapping was conducted each autumn and spring over five years to enumerate the local population of potoroos and to describe their morphometrics. The local long-nosed potoroos were larger in size than those recorded to the south on mainland Australia, but smaller than those in north-eastern NSW, supporting the concept of a latitudinal cline in body size. Sexual dimorphism was observed, with adult males having larger body weights, head lengths and pes lengths. Between one-third and two-thirds of all males and females were captured in only a single trapping session, indicative of low levels of survivorship and/or high levels of dispersal or transience. Males regularly overlapped at trap sites with females, more so than with other males, while females rarely overlapped at trap sites. Barren Grounds Nature Reserve supported a larger number of potoroos and a greater degree of home range overlap between individuals.

The Impact

Inputs and losses from Giant Parramatta grass [GPG, Sporobolus indicus (L.) R. Br. var. major (Buse) Baaijens] soil seed banks were quantified on the North Coast of New South Wales. Monthly potential seed production and actual seed fall was estimated at Valla during 1991-92. Total potential production was >668 000 seeds/m2 for the season, while seed fall was >146000 seeds/m2. Seed fall >10000 seeds/m2.month was recorded from January until May, with further seed falls recorded in June and July. The impact of seed production on seed banks was assessed by estimating seed banks in the seed production quadrats before and after seed fall. Seed banks in 4 of the 6 sites decreased in year 2, although seed numbers at 1 damp site increased markedly. Defoliation from mid-December until February, April or June prevented seed production, reducing seed banks by 34% over 7 months. Seed banks in undefoliated plots increased by 3300 seeds/m2, although seed fall was estimated at >114 000 seeds/m2. Emergence of GPG seedlings from artificially established and naturally occurring, persistent seed banks was recorded for 3 years from bare and vegetated treatment plots. Sown seeds showed high levels of innate dormancy and only 4% of seeds emerged when sown immediately after collection. Longer storage of seeds after collection resulted in more seedlings emerging. Estimates of persistent seed banks ranged from 1650 to about 21260 seeds/m2. Most seedlings emerged in spring or autumn and this was correlated with rainfall but not with ambient temperatures. Rates of seed bank decline in both bare and vegetated treatment plots was estimated by fitting exponential decay curves to seed bank estimates. Assuming no further seed inputs, it was estimated that it would take about 3 and 5 years, respectively, for seed banks to decline to 150 seeds/m2 in bare and vegetated treatments.
