“…On average the post-fire age at DW is 19 years (range 9-23 years) and at WCP 11 years (range 5-18 years), indicating that most WCP sites have undergone fires more recently than DW. As previously stated, regular fire events can stimulate the reproduction and recruitment of many eucalypts (Burrows et al 1990;Ruthrof et al 2003), including E. wandoo, resulting in more budding and flowering events as is likely occurring in WCP. In contrast, less regular fire events, like the situation at DW, may result in less regular 475 reproductive efforts.…”

“…Fire is typically an agent of change that alters the structure of woodlands (Penn et al 2003;Greenberg and Waldrop 2008;Close et al 2009), assists with the regeneration of trees and shrubs by enhancing seed release and establishment (Burrows et al 1990;Mercer 1994), and can stimulate flowering in many tree species (Pyke 1983;Lamont and Downes 2011;Shepherd et al 2011). Mass recruitment of eucalypts can 465 occur after fire events (Wellington and Noble 1985;Ruthrof et al 2003).…”

Living (and reproducing) on the edge: reproductive phenology is impacted by rainfall and canopy decline in a Mediterranean eucalypt

Many of the worlds' forests and woodlands are currently showing symptoms of declining condition due to a range of factors, including changing climatic conditions, drought, and insect herbivory. Altered abiotic and 25 biotic conditions can influence the condition of trees which can, in turn, affect tree reproductive cycles.However, the potential impact of tree decline on reproductive cycles has rarely been examined. This study investigated the influence of canopy condition on the reproductive cycle of Eucalyptus wandoo in southwestern Australia. Canopy and seed trap monitoring were used to assess bud production, flowering, fruiting and seed fall over 12 months at 24 sites across two locations (Dryandra Woodland and Wandoo 30 Conservation Park). Time since last fire, rainfall, ambient temperatures and the condition of individual trees were recorded. We found that bud production, flowering and fruiting was correlated with tree condition:healthier trees were generally associated with higher reproductive effort. Time since last fire was also strongly related to the reproductive efforts at both locations. Declining annual rainfall and increased temperatures also an impact on reproduction, made evident by the aborted flowering in Dryandra Woodland. 35Decline in tree condition, coupled with changes in climate, have major implications for flowering phenology of this species and have the potential to alter reproductive effort, recruitment, and future population dynamics. Consideration of these issues should be incorporated into the conservation management of E.wandoo and similar Eucalypt species. 40

“…Mean germination time (figure 2) was 15.10 ± 0.66 days for P. pinaster, 15 6.78 ± 0.56 and 6.56 ± 2.75 days, respectively) and the ash treatment with a germination rate of 0 % gave a null mean germination time.…”

“…The first germinations occur 6 days after sowing, and in almost all the treatments the most notable germination peak starts around day 8 [6] found that Eucalyptus wandoo regenerated much better on ash beds than on mineral soil, as also did Pinus coulteri [38], P. banksiana [10] and P. palustris [26]. Burns (1952;in [6]) attributes this exceptional regeneration to the increase in pH and the nutrients available to seedlings. Other authors [13,19] [25], Thomas and Wein [32] and Trabaud and Casal [36].…”

-Many studies have found that ash beds favour seedling growth, but the effect of ash on the germinative behaviour of tree species has received little attention. We therefore designed an experiment in which Pinus pinaster, P. radiata and Eucalyptus globulus seeds underwent four different ash treatments and one control. The treatments chosen were three solutions of ash in water (0.5, 1 and 5 g L -1 ) which were used to periodically water the seeds of each species, and a treatment in which a certain amount of ash was applied directly to seeds which were moistened with distilled water only. Six replicates of 30 seeds per replicate from each species were used for each treatment. Seeds were incubated on a double layer of filter paper in Petri dishes under laboratory conditions. Germination counts were taken every 2 days until the end of the germination period. The results indicated that ash (in the quantities and under the conditions studied) had no postive effect on the germination of these species. The ash solutions did not significantly alter the germination rate with respect to the control. Only the germination percentages obtained in the ash treatment markedly reduced the germinative capacity of P. pinaster and P. radiata and had a completely inhibitory effect in the case of E. globulus.

Plants, plant communities and habitats are exposed to serious conservation threats in their natural environment. The negligent man's action contributes to endangered the biodiversity in Mediterranean regions. It has been considered that urban spaces (green spaces) can help to mitigate these threats as they have good potential for implementation of phytogenetic reserves, due to the lowest incidence of threats in plants and communities, such as rural fires, invasive plants, intensive agriculture and the wild herbivory. As green spaces consume huge quantities of water, it is important to highlight the use of vegetation well adapted to Mediterranean climate and those areas could also be elected for raising awareness among citizens. So, in this document we attempt to explore the importance of green spaces as a way of mitigate the decrease of occurrence of some species. The analysis used for this study was based on bibliographic sources, as well as data collected by the authors of this article. It was also developed the concept of using native plants, with resources at local ecotypes, as a tool for adaptation and resilience to climate change, increasing the identity of the landscape and reducing green spaces maintenance costs. In this way, green spaces can be as sustainable as possible with a large seasonal change, depending on the diversity of species introduced in landscape design. They also allow to get positive profits on economy, environment and society at local level.
