Abstract
A unique, two decade-long partnership of a government research organization (Botanic Gardens and Parks Authority) and an industry partner (Hanson Construction Materials) has enabled the restoration and management of Perth's Banksia woodland after sand extraction to be seriously tackled.

Climate change is increasing the frequency and intensity of drought, and seedling response to a recurrent pattern of drought stress is necessary to understand vegetation establishment patterns in particularly for ecological restoration and conservation projects. A controlled environment study investigated seedling physiological response of framework Mediterranean tree species to simulated successive droughts. Six-month-old seedlings were grown in 1.0 m tall pots to emulate deep soil profiles and...

Ecosystem functionality is an increasingly important objective of ecological restoration. Despite this, a few studies have rigorously assessed reproductive functionality within restored plant populations, and it is largely assumed that pollinators follow restoration of plant communities—“build it and they will come.” Here, we applied an ecological genetic approach to determine the impact of spatial separation on mating in Banksia menziesii (Proteaceae), a dominant bird-pollinated species of Bank...

Topsoil is a valuable resource for revegetation of mine sites as it contains seeds of plant species indigenous to the local environment. As mine site restoration is undertaken after the completion of mining, it is a common practice to stockpile topsoil in preparation for restoration activities. While many studies have found a decrease in seedling emergence with increasing stockpile age in temperate regions around the world, a few examine the effect of stockpile age on topsoil seed bank and seedl...

Seasonal drought and heavily impeded soils reduce restoration success in Mediterranean-type postmine soils, where up to 90% seedling mortality has been observed after 2 years. To alleviate these barriers, amendments were incorporated into the soil profile of a freshly mined sand quarry. Within the quarry, three 223 m2 replicate sites contained two substrate amendments: 12% v/v native-sourced mulch or gravel incorporated within the top 50 cm of the soil profile. Three remnant sites provided a “na...

Limited success of restoring framework banksia-woodland species has been attributed to the failure of seedlings to establish deep root systems before the onset of the summer drought. The present glasshouse study investigated how optimising nutrient application during nursery production may increase new-root production after outplanting. Two experimental streams were established to (1) optimise nutrient application rates during nursery production and (2) utilise nutrient-loading techniques to imp...

The major threatening processes to natural ecosystemsglobally are anthropogenic, through changes in land useand degradation. A key strategy to address thesedamaging processes is to implement ecologicalrestoration programs. Ecological restoration involves therepair or creation of biological communities, ideallyrepresentative of the composition, diversity andfunctionality of the pre-disturbance habitat. Theinternational community recently committed to a newtarget to restore 15% of degraded ecosyst...

Rarely assessed in the success of ecological restoration projects is the maintenance of genetic variation in restored populations and, critically, their offspring. A founding population sourced from a limited genetic pool of nonlocal provenance seed can result in genetic bottlenecking and inbreeding, potentially reducing future population resilience and restoration success. We used microsatellite markers to assess the genetic variation of natural and restored populations, and their offspring, in...

Seedling establishment in heavily compact soils is hampered by poor root growth caused by soil chemical or physical factors. This study aims to determine the role of ethylene in regulating root elongation through mechanically impeded sandy soils using Eucalyptus todtiana F. Muell seedlings. Concentrations of ethephon (1, 10, and 100 μM) were added to non-compact soils, and endogenous ethylene production from seedling roots was compared to ethylene production of roots grown in physically compacte...

Five experiments were implemented to collect information related to the effects of fluazifop-p-butyl (active chemical in grass selective herbicides, Fusilade® and Fusilade Forte™) on seed germination, seedling emergence, growth and health of species native to southwest Australia (a grass and non-grasses), together with several co-occurring introduced species (grasses and a non-grass). Experiments investigated effects of herbicide concentrations, seed burial depths, seed-sowing times since herbic...

The restoration of vegetation post mining is particularly challenging in extreme conditions such as Mediterranean systems where soil moisture is limiting, soil temperature fluctuates dramatically, and soil carbon is very low. In such systems, soil microbial communities may play an important role in attenuating extreme conditions. Thus, vegetation establishment on such sites may be curtailed by depauperate soil communities. Soil fungal communities, in particular, are essential for nutrient turn o...

Ecological restoration, when implemented effectively and sustainably, contributes to protecting biodiversity; improving human health and wellbeing; increasing food and water security; delivering goods, services, and economic prosperity; and supporting climate change mitigation, resilience, and adaptation. It is a solutions-based approach that engages communities, scientists, policymakers, and land managers to repair ecological damage and rebuild a healthier relationship between people and the re...

Plant interaction studies provide a good understanding of the roles of key species, which can assist restoration of natural ecosystems. Among the interactions, facilitation and competition are known to affect ecosystem structure and function. We investigated whether a deep-rooted species could positively affect surrounding seedlings through hydraulic redistribution during dry months. We conducted two experiments in which seedlings from two species were growing together or isolated from source pl...

Restoration is becoming an increasing global priority. Particularly in high impact developments like open cut mining, restoring ecosystems to pre-disturbance states is difficult but essential. Successful restoration of vegetation communities requires complex achievements of cover, density, community composition, species richness and structural elements. This study synthesizes 10 years of monitoring surveys to measure restoration success in six mining operations in the semi-arid Pilbara of Wester...

Translocation of threatened species is challenging in semiarid environments, especially when seeds are the principal means of in situ establishment. Worldwide, the overall success of translocations using seeds is highly variable and generally unpredictable. Most seed-based translocations are embarked upon with limited understanding of the species’ seed biology or the nuances of the local abiotic environment in which to guide restoration approaches. For instance, within Australia just 14% of thre...

Demand for restoration of resilient, self-sustaining, and biodiverse natural ecosystems as a conservation measure is increasing globally; however, restoration efforts frequently fail to meet standards appropriate for this objective. Achieving these standards requires management underpinned by input from diverse scientific disciplines including ecology, biotechnology, engineering, soil science, ecophysiology, and genetics. Despite increasing restoration research activity, a gap between the immedi...

Vegetation structure and plant species diversity of restoration sites are predicted to directly affect pollinator attraction, with potential impacts on gene flow, reproduction, genetic diversity of future generations, and ultimately restoration success. We compared Banksia attenuata R.Br. (Proteaceae) in a low species diversity restoration site and an adjacent natural remnant. We assessed fecundity genetic diversity in adult plants and their offspring, mating system parameters and pollen dispers...
