  text: Silvopastoral use in native forests could impact population dynamics of key
    tree species, with contrasting effects at different life cycle stages. Prior studies
    in South American temperate forests have mainly focused on initial stages, lacking
    a comprehensive understanding of the entire life cycle within productive systems.
    We assessed the population dynamics of two key species of mixed forests in northern
    Patagonia (Austrocedrus chilensis and Nothofagus dombeyi) under two silvopastoral
    use intensities (high vs. low), using demographic techniques and population projection
    models. Over 3 years, we quantified vital rates (survival, fertility, growth,
    reversion and stasis) and used matrix models to calculate deterministic population
    growth rates (λ). High-intensity silvopastoral use had predominantly negative
    effects on the elements of the projection matrices of A. chilensis, whereas N.
    dombeyi exhibited mostly positive or no changes. As a result, projections indicated
    slight population decreases for A. chilensis (mostly λ < 1) at high silvopastoral
    use levels compared to low levels, while N. dombeyi showed similar projections
    (λ ≅ 1) between use levels. Decreased λ for A. chilensis resulted mainly from
    lower adult tree survival, while early life stages had limited influence on λ
    for these long-lived species. In summary, silvopastoral use affects population
    dynamics of key tree species of these mixed forests of northern Patagonia, with
    implications for sustainable management. Our findings highlight the importance
    of considering the entire life cycle and suggest targeted practices to enhance
    A. chilensis populations.
acknowledgement: We would like to express our sincere gratitude to the owners of the
  estates, Lisandro and Oscar Lanfré, Roberto Criado and Yayo Tillería, for allowing
  us to conduct our research on their properties and for generously sharing their
  time and knowledge throughout these years. We are also deeply thankful to our field
  assistants, Matías Scotti, Clara Pissolito, Noel Szudruk, Mariano Varela, Ian Mott,
  Brisa Guenuleo, Nicolás Bistolfi, Facundo Gómez and Belén Vallerga, who tirelessly
  collaborated in the arduous tasks of monitoring and data collection, even in challenging
  weather conditions. We are grateful to CONICET for providing the doctoral scholarship
  to D. Arpigiani. This study received partial financial support from the Agencia
  MINCyT (PICT 2015-1692) and the Universidad Nacional de Río Negro (PI 40-B-478),
