  1. Figure 1: Age Structure and Sex Ratio PMWHR Spring 2005 Total Herd Size = 139 Horses Known Age to 9 years Estimated Age 10-25 years

  2. Figure 2: Mare Pregnancy Results PMWHR Spring 2005 Total Mares = 67 Known Age to 9 Years Estimated Age 10-19 Years

  3. Figure 3: Mare Interchange Activity PMWHR 1998-2004 Number of breeding age mares (age > 2) = 551 Number of foals = 295

  4. Figure 4: Harem Interchanging Mares Losing Foals - PMWHR 1998-2004 Numbers indicate the number of interchanges per mare. N= 18 mares

  5. Figure 5: Ages of Interchanging Mares PMWHR 1998 - 2004 N = 208 Mares

  6. Figure 6: Herd and Foal Crop Sex Ratio - PMWHR 1971-2004 Even numbers of males and females is represented by a sex ratio of 1. All Data Approximate
