Limited funding is a major barrier to implementing ambitious global restoration commitments, so reducing restoration costs is essential to upscale restoration. The lack of rigorous analyses about the major components and drivers of restoration costs limit the development of alternatives to reduce costs and the selection of the most cost-effective methods to achieve restoration goals. We conducted detailed restoration cost assessments for the three most widespread biomes in Brazil (Amazon, Cerrado, and Atlantic Forest) and estimated the restoration costs associated with implementing Brazil?s National Plan for Native Vegetation Recovery (12M hectares). Most surveys (60?90%) reported using the costly methods of planting seedlings or sowing seeds throughout the site, regardless of the biome. Natural regeneration and assisted regeneration approaches were an order of magnitude cheaper but were reported in < 15% of projects. The vast majority of tree planting and direct seeding costs were incurred during the implementation phase, and nearly 80% of projects ended maintenance within 30 months. We estimated a price tag of US$0.7-1.2 billion per year until 2030 to implement Brazil?s restoration plan depending on the area that recovers through natural regeneration. Our results offer valuable insights for developing strategies to make restoration cheaper and to increase its cost-effectiveness for achieving diverse benefits in Brazilian ecosystems. Our survey also provides a starting point for sound assessments of restoration costs and their drivers in other biomes, which are needed to reduce the financial barriers to scaling up restoration at a global scale.

Pollen viability studies are essential for high production of fruits and seeds, as well as for genetic improvement and conservation strategies. The objective of this work was to investigate the most suitable culture medium for in vitro germination of pollen grains and pollen tube growth of 11 wild Passiflora species and to examine the viability by means of histochemical testing with 2% Alexander?s solution. This is the first study to provide data on the pollen tube growth of passion fruit. For in vitro germination, two culture media were used, BK and SM, both supplemented with different concentrations of sucrose (5, 10, 15, 20, 25, 30 and 35%). The experimental design was completely randomized in an 11×7 × 2 factorial scheme (species x sucrose concentrations x culture media). Sucrose influenced the germination of pollen grains and the pollen tube growth. P. edmundoi had the highest germination rate (89%) and pollen tube length (2.6 mm) in SM culture medium supplemented with 30% and 15% sucrose, respectively. Regarding the histochemical analysis, all the Passiflora species presented high percentage of viable pollen grains (above 79%). The information obtained in this study allowed identifying the most suitable culture medium for each Passiflora species, helping in the choice of male parents with high potential for fertility, to maximize the potential success of controlled crosses in genetic improvement programs. The results can also support studies of the conservation of pollen grains.
