Howea Palm Survival and Growth Under Soil and Drought Treatments

A 30-month common garden experiment on Lord Howe Island measured the survival and growth of two endemic palm species, Howea belmoreana and Howea forsteriana. The dataset includes counts of surviving plants per replicate and individual plant measurements of height and leaf number at two timepoints. This controlled study investigates the effects of soil type, soil sterilization, and drought treatment on plant phenotypes.

Use Cases

• Analyzing survival rates based on soil type and drought treatment.
• Modeling plant height and leaf count growth over time.
• Comparing phenotypic responses between Howea belmoreana and Howea forsteriana.
• Assessing the impact of soil sterilization on plant establishment.

Strengths

• Data originates from a controlled, 30-month experimental study.
• Includes measurements for two distinct endemic palm species.
• Funded by a specific NERC grant (NE/M015742/1) and authored by researchers from Imperial College London.

Limitations

• Column names and exact row counts are not provided in any source.
• Metadata such as license, author, and size are inconsistently reported or missing across platforms.
