Conclusions and future needs

Conclusions and Future Needs

  • Herbarium records invaluable

  • Increase effort to collect invasives

  • Deposit duplicates at regionally significant herbaria

  • Increase funding for databasing invasives specimens

  • Exploit emerging technologies for data sharing
