Figure 9. Key summer range (KSR) use by horse population and human presence. Data are for use from May to September. Human presence is presented as per cent of its highest year. Human presence includes private sector activities, educational/commercial activities and research/management activities. Human presence was generally greatest during the horse breeding/foaling period (May–June).
