Dorycnium hirsutum and D. rectum are perennial legumes which may have potential for use as pastures for the control of groundwater recharge in southern Australia. Little is known about the quality of the forage of Dorycnium species for grazing livestock or how these species respond to cutting. The effect of cutting height on plant survival, production of dry matter (DM), the proportion of leaf, edible stem (approximately <5 mm diameter) and woody stem in the DM and the nutritive value of the edible components was investigated. Biomass above five cutting-height treatments (uncut, ground level, 5-8 cm, 10-15 cm and 15-30 cm above ground level) was removed at 8-week intervals from plots of D. hirsutum and D. rectum from September 2002 to July 2003. In both species, plants subjected to lower cutting height treatments produced less DM above the height of the cut than those cut at higher heights. DM production declined over time in all treatments. Plants cut to ground level failed to regrow after the second harvest in D. hirsutum and the fourth harvest in D. rectum. Thus, these Dorycnium species were susceptible to high severity defoliations at 8-week intervals. Negligible inedible woody stem was present in regrowth of both species after 8 weeks but D. hirsutum regrowth had a higher proportion of leaf (0AE72) than D. rectum (0AE56). Plants left uncut accumulated a large proportion of inedible woody stem in the DM (0AE69 in both species) by July 2003, particularly at the base of the plant. Edible DM from regrowth of D. hirsutum and D. rectum had crude protein (CP) concentrations of 120 and 150 g kg )1 DM; dry matter digestibility (DMD) values of 0AE45 and 0AE58; organic matter digestibility (OMD) values of 0AE50 and 0AE64; neutral-detergent fibre (NDF) concentrations of 370 and 290 g kg )1 DM; and aciddetergent fibre (ADF) concentrations of 260 and 210 g kg )1 DM, respectively. Medicago sativa, grown under similar conditions, had higher digestibility values (0AE63 DMD and 0AE66 OMD) and similar CP concentrations to D. rectum (140 g kg )1 DM), but higher concentrations of NDF and ADF (410 and 290 g kg )1 DM). Leaf material from both Dorycnium species had a higher nutritive value than edible stems, with DMD and OMD values of leaf of D. rectum being 0AE68 and 0AE74 respectively. Uncut plants had a much lower nutritive value of edible DM than the regrowth from cut treatments; older material was also of a lower nutritive value. The relatively low nutritive value of even the young regrowth of Dorycnium species suggests that forage quality is a major limitation to its use. Forage of Dorycnium species could be used during periods when other sources of forage are in short supply but infrequent grazing it is likely to produce forage of a low nutritive value.

Enhancing Multifunctionality in Agricultural Landscapes with Native Woody Vegetation

The re-integration of native woody vegetation within agricultural areas has the potential to support multifunctional productive landscapes that enhance livestock welfare and restore habitat for native wildlife. As there is minimal research on this issue in Aotearoa New Zealand, this study aimed to identify species of native woody vegetation and propose spatial configurations and site designs to increase multifunctionality on a case study site. The three components of a multifunctional agricultural landscape focused on in this study were (1) enhancing foraging opportunities for livestock, (2) optimizing shade and shelter, and (3) establishing native bush bird habitat. During the first phase, sixty-three suitable species were identified and assigned scores based on the primary objectives and site constraints. This produced four optimized plant lists, one each for the three multifunctional components identified above and one combined multifunctional list incorporating those scores with additional environment and soil scores. The second phase used design thinking methodology to strategically locate these plants within an established case study site. Nine different planting configurations (three for each multifunctional component) were proposed and then, informed by site-specific opportunities and constraints, located on the case study site to produce three individual site designs. Finally, these three site designs were combined to propose an exemplar of a multifunctional agricultural landscape. The results indicate that reintegrating native woody vegetation has the potential to contribute toward multifunctional agricultural landscapes, proposing species and spatial layouts from which further investigation into livestock foraging, increased shade and shelter, and restoration of bush bird habitat can follow. This research advances sustainable land management practices by offering valuable insights into future agricultural landscape design.

“…Some species of Astragalus L. (e.g. Cicer milkvetch) have shown potential in dry hill country (Douglas et al 1996). This legume genus comprises c. 3000 species and, while a number of these species are toxic for livestock (Rios & Waterman 1997), some others may be suitable for New Zealand hill country.…”

The issues currently limiting the performance of forage plants in hill country are largely unchanged from preceding decades. Low soil pH/high aluminium, low soil phosphate and low soil moisture or summer dry conditions are all ongoing problems. Furthermore, predicted climatic changes in many regions will only intensify soil moisture stress. Forage breeding programmes in the 1970s and 1980s delivered a range of cultivars that improved hill country productivity, but small market size for seed has not been conducive to widespread success of these cultivars or to provision of dedicated plant breeding programmes for these farming systems. Intensification is however driving renewed interest in forages for hill country. A wide range of genetic resources is now available to breeders for better adaptation to these conditions. These include large germplasm collections within existing species, germplasm for interspecific crosses, and potential "new" species which have evolved appropriate adaptations at their point of origin. Advances in genomic technologies offer potential to provide accelerated, more targeted selection of germplasm. This would be particularly valuable for traits that are under complex genetic control, or are more difficult to visually assess, such as physiological and root characteristics. Adjustments in pasture management will be necessary to capture the full potential of new germplasm, while tools to improve pasture establishment and renewal (e.g. new herbicide tolerant brassicas) are also needed to enable its successful introduction. The amalgamation of seed companies into large international enterprises adds potential scale to what has traditionally been a localised issue, making the commercial proposition of developing and marketing such specialised products more attractive. These developments, combined with improved seed distribution technologies, should provide a great opportunity for future hill country farming.
